AITAH for letting my cousin play white elephant?

[u/HedgehogFun6877]

My (30m) parents threw a Christmas party and we always play white elephant/dirty Santa. We brought two gifts for my wife (27f) and I. While my wife was feeding the baby, the game started. My little cousin said he forgot a gift so I told him he could use one of ours. When my wife came out I told her and she seemed fine and we played together. At the end I picked a different gift to steal than she wanted, but again she seemed fine. We got home and she told me she was really upset that she picked out the gifts to bring and than didn’t get a change to play. It’s just a game and she didn’t say anything in the moment so I’m confused why she’s mad now. All the gifts were just stuff that we can buy whenever. I really didn’t think she’d mind that I let my cousin play instead. AITAH?

"Little cousin" was apparently 15. With 15 it's completely his own fault for not bringing the gift. If it was a child of something like 8 years OP at least would have gotten a point for having good intentions, even though he failed at it. But a 15 year old boy is old enough to keep track of things

Where did you see the age mentioned?
