to be blunt, nobody makes fun of people if your skinny or of normal size. Examine yourself and how you deal with people. it appears you got alot of enemies. Trust me, it aint yo size they gettn mad at you aboutPeople tell me....need advice?
you really seem to bother yourself much with such things... you know that you can fight and have the ability for that... so damn everybody thinks otherwise.... you shall have high self esteem, it's not fighting that will make you great or hero. Strength is in being having the ability to harm but with also the virtue of being merciful and forgiving. Live in peace, these are trifles or otherwise to show them your fighting you will lose other people, which are those whom you will fight with. :)
People of all ages are harsh. They talk about skinny people being so fragile, fat people that are so big they can't even sit in a regular size chair, things like that. If I was you I wouldn't worry about what people say or do. Sure they can make their threats toward you, but they are just showing their ignorance. Try to let it go as long as possible. Be the better man.
