I'm not talking about when they are angry (can't say I like that do the however). Usually this is teenagers, and when they are with their friends. They're presumably having fun, which is great. But then they start shrieking seemingly out of nowhere and shouting things at the top of their lungs even though the people they are talking to are literally right there. This happens in indoor places, such as the mall, bus terminal, and even doctor's offices. It's almost as if they can't control themselves.

The weirdest thing is that parents don't seem to tolerate behavior like this in young children. A 2 year old throwing a tantrum will get told to "knock it off" (even though it's perfectly understable behavior from a toddler) but no one makes any effort to correct teenagers. So my question is, do they not understand that these aren't appropriate places to act like this? Do they not care? If this was only happening with a few kids I would assume that they had a disorder of some type, or that their parents hadn't taught them how to act. But it's ALOT of them. Not all, but a lot.

I was a depressed "emo" kid at that age who went to a small special ed school...so I honestly don't understand.
