I scare myself

 Boo! Scary kitty from the blog Thinning the Herd

Today the Spanish-word-for-the-day (a Google gadget) tickled me: asustarse, a reflexive verb* which literally means "to scare oneself."  When I think of all the times I get myself spooked, I think this could be one of my most useful words.

It's also the name of a favorite song, and I'm starting to learn it now, so I might have it down really well by Halloween. It's originally a Dan Hicks tune, but here's a version I like by Thomas Dolby. Note the chanted refrain at the end: "It's me I'm scared of..." ¡Por cierto, la verdad!
