Etiquette

Why should I become so frustrated with the apparent lack of etiquette in our society today.  After all, is it not the societal norms that determine what is couth and what is not?  Is it that society has become uncultured, or rather that the culture has changed?  I cling to the mannerisms of a past generation while living amongst a brash people, trying not to let the lack of pleasantries dishearten me, yet it does.  If I had children I would teach them manners beyond the simple sayings of please and thank you, which seems to be the extent of etiquette taught in the homes of today, thought even these small tokens are a feat to instill into the children of today.  Dinning etiquette is all but lost, dancing etiquette has passed into the void, and even the most basic etiquette of conversation is beyond us.  I fear that with the passing of the generations that such things will soon become extinct.
