I just had a very funny thing happen.
Several years ago, Liz and I were pulling into a strip mall and we heard someone yell to us. When I parked my car, this man (and woman) drove up and said he noticed the dent on my driver's side door and he offered to fix it for "a real good price." I wasn't interested since it is cosmetic only and I already know my car will have shit for resale value when it decides to die.
A couple minutes ago, just as I was pulling into Walmart, the exact same thing happened. The exact same man and woman pulled up behind me and made the exact same offer. I'm still not interested. Even in the 5th largest city in the country, it's interesting how many times one can run into the same stranger.
