Hubby and I woke up yesterday morning at 5:30am, to birds chirping. This is about 2 hours early for my birds so I got up to check things out. Once I was coherent enough to understand what was going on, I realized there was an extra chirp in the conversation somewhere. It was one of the smoke detectors making a short chirping noise to indicate the battery was dying. Every time the smoke detector chirped, M&M chirped in response to it.
Um, yeah, so hubby just replaced the batteries in every single smoke detector in this house. No more 5:30am wake up calls for us!
