the card was lowbrow humor. The cultural mismatch is between you and your s/o's parents - they do come off as lowbrow, lower class, ignorant, because of the way they acted after they were politely asked not to. Who buys that kind of card for their son? Why not a "for a loving son" card? And you beauflow, represent the other side of this cultural mismatch - I think that's a very good thing! At least your s/o's mother did try to make up when she said I love you, as you were leaving, and you accepted that and by texting you did keep the lines of communication open.

This is a great example of how something that was not cool, was actually worked out by talking all around. Awesome as ever, beauflow.
