American here, but I agree with a traditionally Polish or German gift. I’ve always thought Polish pottery is lovely.

A kidney donated from a living donor often lasts longer and performs better than a kidney from a deceased donor. Donating a kidney to a stranger can begin a paired donation chain that can result in several people getting kidneys. If you are seriously thinking about donating, I strongly encourage you to do some research with reputable sources, talk to some people who’ve donated themselves, talk it over with your loved ones, and maybe talk to some transplant coordinators at the nearest transplant center. It’s not something to be undertaken lightly, but living donors are saints.

A feed full of cats.

American here, and I’ve never heard anyone seriously answer the phone this way. I did have a co-worker who would answer “Go for Mike” as a joke when he knew the caller. I had the impression it was from silly comedy or sit-com or meme that went around for a while.

I just wanted to add this link to xkcd’s survey results about color names because it’s fun and possibly relevant.
