Cowardice Pays

So, Co-worker has this bike he's convinced I need to use to get from the parking garage to the library and back again (he doesn't use it when he and his wife carpool which is most of the time).
And I was thinking about it, sorta thinking, "Why not?", or that I should at least try it once.
But then this morning, I totally chickened out. I mean, I haven't ridden a bike in ages, and I don't have a helmet, and I like walking.
So, I stick with the usual routine, skip the bike, and am walking from the parking garage to the library, when lo and behold! What is this on the ground? Could it be a crumpled up dollar bill? No, even better, it is, in fact, a crumpled up five dollar bill.
If I had been riding that damn bike, I never would have seen it.

Now I need to figure out what completely frivolous thing to buy with my free five dollars.
