♥ Useless behaviors ♥

I'm far from perfect. I make mistakes. I don't know how to act sometimes.
Much of human behavior has no useful purpose in current society. Everyone has a good behavior nor bad behavior. A portion of these can be called "useless behaviors".

Does we know that the useless behaviors can make people whom beside you feel exhausted, annoying, boring, anger and so on.

So please behave yourself with a good way.
