Always !!! You can lose anything but the glamour ! =D (This is my mom talking) Of course you should behave properly according to each different situation. And if you like to play with boundaries you should be really careful. We live in society and your behavior shows respect or disrespect. ^^

It should just be the outward manifestation of the purpose or purposes you are following in life. Hopefully they are good ones, and hopefully you are being successful in forwarding them. If not, then there are forms for speech and behavior that you can follow to let others feel more comfortable about you-- if this is important to you. You should ask yourself: Do you really care what others are thinking about you? The answer to that question will vary according to how much liquor you have drunk or how many drugs you may have taken, so you should take that into account also.

I recommend speaking and behaving like an idiot for a couple of days. Then you'll understand just how important it is.

Let me answer with a joke, please: If you REALLY don't know the answer to this basic fact, then you don't need that answer! Am I misbehaving ?

It's not important at all. Let's all behave like savages! Or not... :P
