Killed a bug this weekend.

So when I got in the shower like 12:30pm Saturday night (actually early Sunday morning, by that time), I turned around to get my shampoo bar off the soapdish on the ledge in the showerstall, and I saw this three-inch silverfish weighed down with water drops from the shower desperately trying to heave itself up the side of the bathtub. Last time there was a small one in the tub I killed it with the heal of my foot as an act of self-discipline of the flesh - what does it matter to me to kill a bug with my bare foot, so long as my foot isn't injured by it? - but this one was way too thick and juicy and I was a little too afraid of it, so I grabbed my soap-dish and mashed it to pieces and then flushed it down the drain.
