What is it with me and metal boxes?

Apparently it's not just condom machines that are out to get me -- all the metal boxes in the world are looking to pick a fight. You'd think I'd be smart enough to walk away, but no... Yesterday I had another altercation with a metal box and lost (again). This one was, for some reason, screwed underneath my seat in the bus, and it had very sharp corners. So I was not very happy when my foot smacked into it...

Now it looks like my ankle crashed into a rainbow at ninety miles an hour. Y'all be careful -- those darn rainbows hurt more than you think.
