What goes around

This week I found an umbrella on the underground. The umbrella I already have has a wonky spoke and it's so light and effete that I swear I hear it whimper when there's drizzle in the air. So, when I found this big, lumpy, beef of a brolly on the tube, that someone had left behind, did I hand it in to the lost property office? No, I kept it and threw out my old one instead. Does that make me so bad?
