Flasher
My coworkers in the tax office cleaned out their holiday decorations this week. They foisted some Christmas lights on me - not one, but four sets - two multicolored and two bright blue.
I have never in my life* owned a set of colored Christmas lights. My family is of the strictly white-lights-only school. We just don't roll that way. But I couldn't really say no to the tax ladies. If I hadn't taken the lights they'd have given me something even tackier, and I can assure you that there was some phenomenally tacky stuff in those boxes so I chose the least of the evils.
I put the multicolored ones up in my living room window and set them on flash mode just to drive the neighbors crazy.* They look great. The blue ones went along my bedroom window. I kind of want to leave them on all the time because they lend a surprisingly warm glow to my room. Who'da guessed?
* If we're being totally honest here, I once had a small string of blue Christmas lights when I was like 10. I'm not sure what happened to them or where they came from; I think they died young. I like to think that this was a precursor to my eventual falling in love with The Weakerthans.
* Kidding; they always have their blinds down. Also, they are my landlords. I bet they haven't even noticed the flashers.
