Probably one of the gifts for my wife, although that covers a lot of different gifts more and less than $100. On the exact amount, it might be a check I wrote when I was a vet counselor in the 1970s working mostly on GI Bill education benefits on a campus. Mostly between the other vets and me, we could shake loose the benefits in time to pay off their landlords, the electric company, the tuition, etc. But one man was in a terrible spot going to school, and his wife seriously ill, and I just wrote him a check, sent it to his home, and told him it had nothing to do with his benefits, which we eventually got going. FYI vets, the worst prevalent cause of non-delivery of checks was misplacing and forgetting the file number, and people who tried to use their social security number when they still had one of the old VA numbers. Translated into the present, bureaucratic detail. Sometimes guys started out angry with me; then I'd sit down and write them a hair-raising complaint memo for their signature, and they liked me some better. The other best hundred bucks have been fees to adopt rescue animals. While the biggest lie in the English language is the two words "free kitten," the hundred bucks I've put toward several fur friends has repaid many times in companionship, amusement, and to my mind intellectual stimulation -- they don't talk, but they perpetually think and communicate -- ears, eyes, tail, posture, vocalization, gait, etc.
