Chirping

Not a good night.  Smoke alarm needs new battery, first noticed when I awoke in the wee hours.  Not sure from the chirp whether the upstairs or downstairs unit.  I replaced one not long ago.  Transistor batteries not always easy to find.

Eventually just got up, took cell phone for scrolling which I virtually never do between 11 PM and 5 AM,  then back to bed, though did not doze off until the time I had planned to arise.  Gave myself another 45 minutes.  Now some coffee.
