And my poor feet, at the end of the day they're really hurting. The other problem is the dogs. Sometimes you can make friends with them and they'll follow you around. But other times, they can be mean. I've been bitten a couple of times. I can't say as I care much for dogs any more. But it's not all bad, my job. One thing I like is the way meet a lot of people. You learn all about their private lives, too. It never gets boring.
