Can I not be social? I am shy.
That depends. How long have you been shy and not social?
I've always been this way since I was 3 years old.
Perhaps you just need more social interaction. It's not good not to have confidence yourself. I'm sure you can improve your social skills.
No I can't. It's just not in me to be social.
Don't think that way. You can change anybody can. You just need confidence in yourself and put yourself out there.
