Interrupted!

I've been thinking more about being constantly interrupted in lab. It breaks my concentration and it takes time to refocus on a task. It doesn't happen too often at the bench, but often at my desk when I'm trying to concentrate/work through something. As a solution, I think I'm going to try and make signs that let people know if it's OK to bother me or not. Plugging into my iPod hasn't worked so well. Hopefully this will be a successful experiment. I can just point to the sign if someone tries to interrupt, and I avoid feeling like a complete jerk by telling someone I can't talk to them right away, which seems like the expectation when someone is standing there looking impatient.
