Everyone who knew me in college(or earlier, actually) has joked that I am always talking to some stranger. Always, I engage the strange people around me and pick their brain. I find frequently that what most people percieve as a bum would actually be some philosophical genius exploring the world on foot. Dirty and stinking, with so much wisdom ready to share with anyone who forgoes judgement. Also, there are homeless alcoholics who only need someone to listen. I have made men twice my age cry with epiphany. Be wary, but talk to strangers… They may have more to say than you could know.
