I WROTE THIS QUITE A WHILE BACK, BUT CAN’T REMEMBER IF I EVER RAN IT.  IT STILL PERTAINS, SO IF I ALREADY RAN IT I APOLOGIZE. 
“The  cardinal principle of etiquette is thoughtfulness, and the guiding rule  of thoughtfulness is the Golden Rule. If you always do unto others as  you would have done unto you, it is likely that you will never offend,  bore or intrude, and that your actions will be courteous and indeed  thoughtful.” ~Emily Post
“Parents who insist that their children practice courtesy and good  habits at home are doing them a great service, for these habits then  become lifelong and the natural way to do things.  It is then unlikely  that they will ever embarrass themselves socially or in business, for  their unconscious actions will reflect a well mannered person.” ~Emily  Post
 
Need  I say more? Evidently yes based on what I see in everyday life. Just  this past weekend, I observed at least a dozen occasions where this was  NOT being practiced. When I was young I was taught to say please, thank  you, I’m sorry, excuse me and a variety of other niceties that tend to  make life more pleasant as well as show respect for my elders.
Though  the reasons for many things have changed, the act of doing them has  not. For example, in Victorian days a man escorting a woman on the  street would walk on the street or curb side of the woman to keep her  from being splashed by mud. These days, a man still does it, but now  more for safety.
Social  amenities are still in fashion despite women not being the frail  creatures once thought. I know feminists everywhere will hate me, but I  LIKE when my husband opens the door for me, stands when I leave the  table at a nice restaurant, takes his hat off indoors or walks on the  street side. After all these years we have developed an instinct for  being courteous to each other.
As  a society we have wandered away from many day to day courtesies. We as  parents have the responsibility to create the adults of tomorrow and  that training begins at home.  That is pure fact.  I recently overheard a  couple of moms out having lunch complaining about how their kids were  not learning manners at school or in daycare.  HELLO?  Once again many  feminists world wide will be upset with me, but I truly blame some of  this on the parents.  It is not up to the schools or daycare to teach  the children manners.  My highest respect is for the stay at home moms  as they have the hardest job in the world.  Many common courtesies are  no longer practiced by many families and/or enforced by parents, but  that stay at home mom is going to expect certain levels of courtesy and be available to see the beginning of bad habits forming.
One  of the examples of the need for everyday manners is on public  transportation.  Awhile back I was on a subway when a young mother  carrying a baby got on as did an elderly gentleman with a cane.  The car  was full and not one man or teenager got up and offered their seat to  either of them.  I was embarrassed for us as a society!
There are some personal habits that should be addressed, but based on  today’s casual acceptance I will only mention and then leave the  interpretation to the reader: men removing hats indoors,  slouching/posture in general, elbows on the table while eating,  chewing  with your mouth closed,  belching/burping in public,  women in dresses  sitting in a ladylike manner,  disposing of your gum appropriately,   smoking in public,  being a good neighbor,  personal  space/crowding and  the list goes on and on.
I  have seen many well behaved children and truly appreciate the effort  their parents put into their training. I just get so disappointed that  so many other parents are readily allowing less than acceptable in their lives as well as their children’s. The ME  generation does NOT have to be here to stay.  Hubby and I went out for a  nice leisurely afternoon lunch today at a little restaurant we like to  frequent.  It is very quaint and scenic.  Halfway through our lunch a  young family came in (the kids were about 2 and 5).  Mom and dad sat at  the bar and ordered a drink leaving the kids to wander.  HELLO??  The 2  year old wanted something the 5 year old had and when she didn’t get it  started a tantrum that the parents were ignoring and the rest of us were  enduring.  NO ONE said anything!  I was beside myself.  Normally I  would have been pissed, but not said anything.  Today was not normal –  I had a splitting headache and was just beginning to relax when this all  occurred.  I calmly walked over to the parents and asked if they  wouldn’t mind taking the little girl outside to calm her down.  They  were quite insulted by MY nerve as they put it.  I told them I was  insulted by their nerve.  They were clueless!!  I actually had to spell  it out for them that while everyone was trying to endure their little  girl’s tantrum, it was not our responsibility to do so.  We were all out  spending our hard earned money on a relaxing day which did not include  providing daycare for them as their children ran around unsupervised.
While  there are even more situations we could address because our entire life  is full of them (strangers, prejudice, those with handicaps, unexpected  visitors, hospitals, church services, etc… the ultimate rule of thumb  is and always will be the Golden Rule for ALL situations.  
Do unto others as you would have them do unto you.
