Batteries

Tricky little things, they are.

So at almost midnight last night my smoke detector started going off. I was all sleepy and ready for bed. It went off, I reset it. And, repeat. Well I finally took the battery out, but that didn't fix the problem. So I called my local dire department and had a huge firetruck outside my house at 11:45 with four firemen show up, just to tell me, it's the battery. They replaced it, and now I will need to replace all of the others soon. He said batteries need to be replaced about once a year. So praise the Lord, there wasn't anything for my fire alarm to really go off about. :)
