It seems like most of the teenagers are almost always in a bad mood?

Yeesh… I wonder why teens are almost always in a mad mood. They have a good childhood. Alot of them have parents who don't discipline, lots of freedom and an Iphone. They have a good life, I don't see why they should get mad because they get almost everything they ask for.

Puberty + Hormones = obnoxious teenagers.

Just because someone has a 'good life' doesn't mean they don't have their own personal problems. Then add that on to hormones and the fact that they're growing up fast, which is the main reason for a bad mood.

Well I'm happy: D

Not everyone has a good childhood. I agree, some parents don't displine their kids very well, but it's their kids and they have different methods. And an iPhone. Right. Your points are pretty sh*t. They get everything they ask for? Material items do not make everyone happy. Your points do not equate to a happy life.
How old are you? Teens don't have it easy. It's pretty hard.

I'm in a bad mood because I come home from school to a house where no one knows what the hell an inside voice is.
