The world as a whole seems to be dressing down. Formal night should be a minimum suit, Casual nights Dockers and a polo or dress shirt without a tie, as the word implies "casual".
Where I come from, with the exception of the opera crowd, dressed up a lot ot times comprises of starched jeans, boots, a western shirt, a western cut jacket and a bolo tie.
Joey, I understand where you are coming from with the term "TRAIN" and it is put in the correct text. The problem with the world as a whole is the parents are leaving the training (we still call it potty training and not potty advisement) to baby sitters and not actually raising the kids themselves.
I'm sure this answer will draw a pleathera of flaming, but it's all good and simplily MHO.
