I tend to notice the dumb little things no one else does. It's rarely anything important, but it sometimes comes in handy.
Last week my wife and I walked into a grocery store and as usual were headed to the left to pick up some groceries. I stopped for really no reason and looked to the right where the cashiers are, and there were two guys standing there holding an 8 week old beagle pup. They must have been 50 or 60 feet away in a direction I wasn't looking, but I looked for some reason anyway and spotted the little critter.
Naturally, being dog people my wife and I had to go over and say Hi!
