There is a beep in my house. Every 28 seconds. Not a missed-call beep. Not a microwave-ready beep. A something is going on with the smoke detector in Lily's room and I don't know what to do about it beep. Peep on Discovery Kids doesn't drowned out the beep. (Peep-beep, interesting.) Snoring dog doesn't cover up the beep. Clicking computer keyboard doesn't mask the beep. I fear that fiddling with it will only worsen the beep. But I must try.
