I agree too.

I bought my house almost 5 years ago, after my Dad moved in with me.

I can't tell you how many times he has rescue us! Fixed, repaired, replaced. I'd be broke by now!

Wish I could do a quarter of what he does. I swear he has every power tool Home Depot has ever carried; and most of them predate Home Depot. Most of them, I haven't a clue what they are for. I find it very sad. What am I going to do with all of them once he is gone???

Now that he is 80, he often makes a point of saying, "I can do it; not today, maybe not tomorrow, but I can do it. Is it a rush? Should we call someone?" Sometimes I call just to learn the price.
Then I make do until he gets it finished.
