Everyone has their own way of expression and each has reason to be this way. The key to gleaning wisdom from all, even though we do not understand the ways in which they act is to just listen and ponder. Never be afraid of the other unless of course they are violent or physically abusive. You learn about the world much more by hanging around with folks who are much smarter than yourself and who have experiences that are amazing and crazy. You will never grow or expand your view of the world if you play the safe game and look for those just like yourself.
