What's With Uncle Bob?

A Drabble (exactly 100 words) about a mysterious change to a relative.

How Uncle Bob became a vampire is a mystery to everyone who knows him.

I don't recall when it happened, but one night he just disappeared, and two days later he showed up on the local news. Seems that he was caught trying to break into the local blood bank. There were no other details, and when he returned he didn't have a lot to say.

He sleeps a lot during the day, so we don't see him much anymore. It's nice to have him back, although I get a bit nervous when I see him staring at my throat.
