Actually, I'm looking around my apartment and it occurs to me that I could totally have a garage right now. I don't even know where all of this stuff came from. Do you think it's possible the neighbors are sneaking it in through the windows in the middle of the night?

Here's an eleventh way to ruin your garage sale: Let your kid run one of the tables. I have a distinct memory of 'helping' a neighbor with a garage sale when I was about five. I told people that everything was a dollar. That was the last time she asked me to help.

The stuff that's left at the end of a garage sale is sadder than the lint in the bottom of a bargain bin, but you don't have to resort to throwing everything away.
