General expenses are about the same. i.e. utilities, house, etc.
Getting old expenses, I forgot about. Now these are not medical and such but things I now have other's do because I can't or just don't want to. like mowing the yard
Repairs are about what I expected, New house on retirement and those have not hit. However, I planned and continue to save for those.
If you read enough on here, you will come up with just about every expense you can think of! Hurricanes, tornadoes, relatives, as the Farmer's commercial says 'You name it and It's happened!'
The only one that has not happened is run away inflation! And, I hope it does not, and I am not sure how I would deal with it. But, I know I would not work another min to worry about it!
Edit: Any onetime thing that has come up, like a 50th anniversary party, has been able to work into the budget. If it had not we would not do it.
