I don't know why I didn't think of this sooner. Friday afternoon, as we unwound from a demanding week, we (okay, I) taped a plastic cup to the outside of one of our windows, and put a label on it that said "TIPS". And darned if people didn't leave tips--including a boy who could barely reach high enough to leave his dime. Okay, we didn't make enough to significantly alter our lifestyles, and at any rate Harry made off with the entire plunder. But it just reaffirms my faith in human nature. No, really, the enthusiasm with which people played along made me realize how willing people are to engage with something a little oddball in their day.
