I was walking by a store today which had one of those rent-a-cop security guys in front. He was greeting customers as they left the store and saying hi to people who were walking past. But when I walked past him, not a word. He then says hi to the woman walking behind me. Later as I was leaving, he greeted a man about 8 feet in front of me, but once again avoided me.
Maybe it had something to do with the shirt I was wearing today:
(Jason says I can't wear this shirt at school because it might be deemed offensive.)
