Smitten recently asked the question: What's your cell phone background picture?
I thought that was cute and really interesting. It's not something I had really ever thought of, but it does say something about the person, no matter how minute.
Mine is of a girl I was standing at a bus stop with. The sun was just coming up and it was raining, so she had her umbrella out, which was yellow. This just reminded me of the girl with the yellow umbrella from How I Met Your Mother, which is my favourite show, and it's simultaneously a little inside joke with myself and a reminder to keep looking and not become jaded. I'd say that says somethin'!
