There's no fire!
Sorry for the beeping, Dave and Alexia. Thanks for the texts, and now that I've teetered on my footstool and changed the 9V, the beeping is over. I didn't realize it was the detector closest to the wall. Super sorry. Have a wonderful, sunny time at Cabo! I want photos. Oh, and thanks for Francesca invitation last night, hope the wine was flowing. I'm going to reply to your email, A.
