This is the bathroom sink at work. The bathroom never has the necessary trifecta - tp, soap, paper towels. But guessing games are fun...unless you guess wrong. Anyway, I spy with my little eye...an olive? a grape? rabbit poo? Of course I wouldn't touch it so I ran the water (I know, very not green of me - but this was in the name of science) to make the object roll around. I have determined that it is a grape. MaryCatherine suggests that it will be in the sink long enough for it to ferment and make wine. Bets, anyone?
UPDATE! UPDATE! The grape is gone and MC suspects that someone ATE IT. In this place, I wouldn't doubt it.
