As usual, I was telling a friend about how much I enjoyed working around my house. Doing small things when they pop up makes home life more enjoyable.
As an example, I saw that their kitchen faucet splashed the water around more than it should. They were amazed at how nice the water ran (and didn't splash on the counter) after we replaced the aerator ($3). It's something that most people don't think about doing. It was the hard water that caused the problem and gunked up the old aerator, so I suspected that we would have to do the same thing to the vegetable sprayer. Yep. $5 later, they could finally spray their broccoli without wetting their shirts at the same time.
Flaky light switches, loose doorknobs, droopy curtain rods, missing weather stripping, etc. There are lots of little jobs that many homeowners never think about doing, but which are easy and inexpensive to do. These little things make a big impact.

PS: Little fixes also make great favors for those elderly neighbors to show them how much you like having them around.
