if it ain't broke, don't fix it

Yesterday I finally got ahold of the right sort of wrench and fixed the cat tree so it doesn't wobble so much. Today I fixed the vacuum cleaner, which somehow had most of the hose clogged up with rug fuzz. I have no idea why it decided to do that. But I unclogged it, and now the whole works actually works the way it's supposed to.

It's not quite in the "fear me, I have tools" category, since fixing the vacuum cleaner didn't involve any tools, but it's satisfying anyhow.
