Watching people in public doing something weird and making up stories about them based on that weirdness is a fun activity for me. The latest incident which had me laughing out loud to myself is that I was standing in the shoe department looking at getting a new pair of no-brand converse and saw a middle aged balding man touching/holding various shoes and looking thoughtful. Little girl's shoes, men's slippers, boots, pumps then he'd noticed I was watching him or snapped out of it or whatever and he quickly wandered off. A few minutes later he was back touching on all the shoes again. I made up a little story about Thomas the Toe Toucher.
