My bad points,good points

I am cold about a lot of things.
My friends say that I am not interesting and scary.
Certainly,I can't have interest things regardless of me.
But,I can concentrate my interested things than people.
The other bad point is that I am moody.
This is said that I was from junior high school.
I don't grow up.I must change myself.
The most good point is I am systematic,and mental age is young.
If I will be adult,I will never forget a childish mind.
