I was speaking of clothes noot manners! get that straight. Plus sorry, but we don't want to be all up-tight in uncomfortable, tight suits, etc. This generation is obviously more level-headed on that point. What the points of going to a concert and sitting there for hours in an unconfortable outfit that bugs the shit out of you, you just can't enjoy it then. As for tradition, ha! Tradition is a things that ruins our process of imagination, it doesn't let us go further in certain areas, it makes us stay back in 1700, when he tradition was made, we are in the 2000s now, c'mon people, let's ditch that crap, that was sooo last century ago. Just do what you do, there will always be someone who doesn't like you because of what you do, REMINDER: I am talking about clothes not etiquette, you'll just have to learn everyone does things differently, and they aren't going to change because one person doesn't like what there wearing. Plus what buisness is it of your's as to if they have a T-Shirt on, or not, you were their to enjoy the music, not to observe and critize a person wardrobe. Over the last year too, I've realized that adults are very stubborn, for example if someone came up to one of you and said for example "What are you wearing that white sweater for, it's all about blue." Would you go home and change, just like adults children are opinionated and just like adults they are not going to change their opinion, so just do what you do, regardless.
