LOL! One of the ladies in my prayer group went three weeks without heat during December.
Try going three weeks without a shower. I should go to the YWCA or something. Sponge baths are all right, I guess.
Hubby had a shower this morning, and the problem did not manifest, so I’m going to get brave and take one this afternoon.
She's probably the self-defrosting prayer group model. They last a long time, too.
