While I was putting my shoes on in the morning, I saw a spider appear near them. Outside the shoes, I mean.
It made me remember this one scene in a Wimpy Kid book I read when I was a kid where Greg spots a tarantula outside and he hits it with his slipper. After he takes a shower, he puts the slippers back on, unaware that the tarantula somehow crawled in there. It's supposed to be funny, but all it did was exacerbate my arachnophobia. Now I check shoes or closed-toe slippers (or whatever they're called) that I haven't used in a while to make sure there aren't any spiders in there.
