2:30 AM What is that strange noise!

OK, I am up at 2:30 getting ice and pillows ready so I can elevate my knee. I hear this strange noise, track it down to the guest bathroom, the toilet did not shut off after I flushed it. No big deal, just turn off the water and run down to Bredfields in the morning for a new one. I slept great after that, woke up around 7:30 and did my exercises. Vera finished her shower, so I went in to shave and shower. No hot water! I go check the breaker and it is OK. Vera cleaned the closet that the water heater is in so I could get to it. Don't ask me why they installed it there, as it is a bear to service. Next time it needs to be changed, I may go through the outside wall. Well, I checked the top thermostat and it is bad, as luck would have it there was new top and bottom thermostats on top of the water heater. Why I had such foresight I will never know. I changed the top thermostat and we turned the power back on. Time to ice the knee while we see if that worked. It did, hot water now, but the bottom thermostat is bad also. After Vera moved some things so I could get down on the floor. I changed the bottom one, turned the power on and checked things out. OK, so I put the covers back on and then the big challenge was getting up off the floor. It was easier this time. Time for more ice and lunch, we ate out on the porch as it is a really nice day. On to the toilet, everything went great there and it was done in about 15 or 20 minutes. Glad I had Vera to make tool runs to the shop for me. I have got to watch her, I think she has her eye on my small Channel Locks. Finally at 2PM I get my shave and shower. With any luck I will not have anything to add here this evening.
Hope all your projects for the day went well.
