Why is it dumb?

No disrespect? Then in the next sentence you call it dumb? Are you intentionally stupid or is being obtuse a congenital thing with you?

You haven't been hurt enough to realize that everyone, and I mean everyone has the capacity to absolutely destroy your life. Once this becomes a realisation you see the world through a very hardcore micro-lense. The only people I want in my life is the ones I know that will not harm me.
