Emo is a term currently used to refer to a subculture of young people (generally teenagers) who wear dark clothing and act in a melodramatic manner. They tend to wear tight clothes, which are usually black. Both male and females will complain about their lives and their families, even if there is really nothing wrong. They will often claim that their parents hate them, even if their parents are actually very caring. They tend to be immature, since their melodramatic demeanor is usually the teen manifestation of brattiness.
The easiest way to reverse this behavior is simply not to put up with it, and to point out their bratty attitude to them (see example 1). It is important to provide the emo kid with both reassurance (see example 2), and tough love (see example 3) It is also important that you ignore any attention-seeking behavior.
The biggest problem with emo kids is that they emulate kids with depression, which makes it harder for the kids with actual problems to get help.Many emo kids write suicide poems for the attention, and as a result it becomes harder to spot the kids who are actually contemplating suicide.
EMO KID: My life sucks. My mom hates me. She won't give me money for the movies.
FRIEND: Your mom gave you money yesterday. You spent it all at hot topic.
EMO KID: I knew it. You guys hate me. Everyone hates me.
FRIEND: We don't hate you. You're just being immature right now.
EMO KID: My teacher hates me. Look, she gave me an "F" on my test. It's just so unfair. I work so hard, and I still fail.
FRIEND: You failed the test because you didn't study, and because you only answered half the questions. Suck it up. Some people have actual learning disabilites. Like dislexia, the one that makes some letters appear BACKWARDS? Take responsibility for yourself.
EMO KID: My life sucks.
DEPRESSED KID: mine too.
EMO KID: My parents cut my allowance just because I got an F on my test. And they wouldn't buy me any eyeliner.
DEPRESSED KID: Nothing I do is fun anymore, I can't sleep, I keep getting headaches, I can't remember the last time I had fun, and my parents grounded me for a month because I "stole" my step-mom's mascara. When I told them how depressed I felt, they told me to stop being emo.
