I ran from a kid because I didn't like him
Can you talk to him instead of running away?
No, I just didn't want to talk to him.
Not talking to the person might be something to do with having social anxiety, lots of people have it. It is a bad habit though, and there are many people out there to help you with it. Taking medication for it is good too, but not doing anything but running away won't help you at all.
Nah, I'm fine. Also I would run from you if we met.
That does sound like a social phobia, I think you'll be much happier in life if you can solve this issue instead of running from it.
