Disheveled guy with a shovel rings your bell shortly after midnight and asks to shovel your walk for a couple bucks. He says he lives around the corner and just wants something to eat. It's still snowing out. What do you do?
Me? I mumbled sure, went back in, waited a couple minutes, then came out and gave him two singles. He asked for three more. I told him I'm not a rich man, and he can stop if he wants to.
Thing is, he just made more money than I have all year, but I feel guilty.
