What do you think about this

My boyfriends family gave me and him a bunch of nice presents for Christmas. I’m so grateful.

However, they gave us a card that had $600 in it and said that it was for both us.

My boyfriend put it in his pocket and I never saw the money.

Do you think that’s rude ? Or do you think since it’s his family, it’s not my place to say anything or have the money.
