It seems that nearly every smoke detector in our house had a low battery tonight. All at different times. In approximate 2 hour intervals. I was woken up at 10:30, 1:30, and 3:30. Let's see how we can turn this grumbling session into a praise session. Praise the Lord for engineers who can create 10 year smoke detector batteries! I placed my order for 6 batteries at 4:30 am.
