March 2: Driver's side windshield wiper blade falls apart. Replaced. (This had been breaking since January, and I had bought a replacement a few weeks earlier.)
March 4: Car battery dies after nearly three years. Replaced March 5.
March 12 (12:45 AM): Upon leaving work, discovered that both low beam headlight bulbs had burned out. Drove home with high beams on. My mom got this car in 2014 and I've never replaced the headlight bulbs, so I guess it was time.
(UPDATE, 3/17/24: The 2009 Toyota Camry has two "headlight" bulbs. If you look the information up online, you will be told that the replacement bulb is a 9005. This is the replacement for the running light bulb. This apparently only comes on when you switch on the high beams. The headlight bulb itself is an X11, which is increasingly difficult to get. They are not interchangeable. I ordered two 9005s, when I actually need two X11s. Turns out I have one X11 that I believe was left in the glove compartment in its package by the previous owner, so I need one more.)
March 13: Television dies. This TV was about twelve years old, so I guess that was due, too.
UPDATE, 3/28/24: Water heater dies, March 26. My mom had subscribed to one of those home warranty companies, which I always saw as a ripoff - anything you actually need done never seems to be covered. Turns out the subscription was left on auto-renewal. It first renewed a week or two after she died, and then again a year later. I had it transferred into my name. They sent someone out yesterday to check the water heater - a covered system - and he confirmed that it needs to be replaced, something that is not covered. I saw some stickers on the water heater itself, which was installed in June 2018, and called the number to see if it is still under the manufacturer's warranty. It is! So now I just have to arrange to have someone remove the old heater, take it to a specific retailer, get a replacement heater, and install it. Still going to cost a lot of money.
Sigh. Life is expensive.
