Powering my camera

I left the power adapter to my nice digital camera at home. So for the last 3 weeks I haven't been able to use it. There hasn't been anything that's gone on that I would have really needed it for, but I still like taking pictures! Luckily I called my family yesterday - it's hard to get ahold of the parents... - and my mom found the cord. She is supposed to be sending it with my watch I left. Now I'm going to call to remind her.
