I Always Get Asked Why Im So Quiet

i get asked this at times,most of the time i'm not interested in what was said or i really don't care.for one i don't trust people to open up to them,i keep things to myself i don't think i'm mean but i been hurt so many times in the past it's best to not say too much till you get to know someone on a friendly level that you trust.i'm interesting in ways but the things i like things like music and fixing stuff,which of course you have to be quite fixing something or you risk fixing it wrong.i guess you could say i walk to the beat of my own drum.
