My nephew is turning 11, and he is into sports and Pokémon. I don't know that much else about his interests! It is a common Uncle Situation.
I could find Pokémon or European football gifts that he wouldn't already have, so I got him a portable Bluetooth speaker. A weird thing to land on. (I spent a lot of time considering some board games, but you not only have to be into board games for those to work, but your friends have to as well.)
Anyway, I continue to stumble through life in this manner.
Uncle Situation would be a decent wrestler name, I think.
