Day 124 #%&$ing Heater Broke




Day 124 #%&$ing Heater Broke





$%&$ing heater broke. Thank heavens we live in the desert, but its still cold here. 2 years ago we had the outside a/c unit fixed on Independence Day. It was 114 degrees out so we had to have it fixed.

That cost us $4,000.

We are about to pay the same amount again probably for the indoor heating unit. Oh joy.
