The lonely guy you just ignored because of his weird antics (talking to himself, joker face, talking to stray animals, insecure and wierd body language, smiling without any reason, blank stare, scanning the sky, waving at planes , helicopters and birds ), I am that guy. :) But I am not lonely , I have a world of my own,a bit different than yours.I live happily there ,not trying to get love , attention and sympathy from others but for happiness which comes from all around me and from within !!
