What do I gag gift when someone say they want “nothing specific”?

Maybe get them nothing?

I am part of the crowd of people that don't want anything. I already make plenty of money, enough to buy anything I might want, yet I live in a mid sized space with the bare minimum (maybe a little bit more than the bare minimum).

I still sleep on a futon.

And having many useless stuff around creates unnecessary annoyance, because I think about those things and worry when I don't use them.

Modelling clay. It can be anything they want.

Sea Monkeys, because brine shrimp are cool.
