Gift giving can be quite the puzzle. I like giving people something special, that's just for them, ideally something that they wouldn't have otherwise. This is tricky, but a wonderful thing when I manage it. I like making people happy.
Therefore, I shall take these things I chose because I thought specific people would enjoy them, and send them to those people, and hope they're enjoyed. Thanks everybody!
I'll also give an example of such a gift. I was at a store once, and saw a bunch of Hallowe'en decorations that were no longer seasonal, off the beaten path. One was a snow globe type thing, but the "snow" was tiny black bats. Swirling it around caused a nifty effect of bats swirling around. Just the sort of thing fizzygeek would enjoy. So I bought it for her. She was thrilled, it made her day.
* Unless the gift is actually relationship-specific (which is rare in my experience) or I no longer like the person (even rarer, I'm still on good terms with most of the people I've ever dated).
