No one likes it when someone takes credit for someone else's hard work. It's the same reason we all hate doing group projects. This guy ran into the interesting problem of his sister trying to Santa-launder his gifts to her kids. Was she just trying to save money? Did she forget to buy enough presents? This feels like the kind of issue that shouldn't be a problem among grown ups, but y'know, Karens are gonna Karen .

Ho ho ho.
