Family traditions are a huge deal. Unless they're flawed in some fundamental way, you probably shouldn't mess with them. After all, they're the best way to bond with your family, especially if it's a family you just married into.
A woman on Reddit who goes by TARRAFs opened up about her own family tradition, which she refused to change for the sake of her daughter-in-law. But now, the DIL and the woman's son are upset, claiming that the Reddit user made things uncomfortable for everyone. So, she asked the AITA community if she really was in the wrong, or if her son/DIL were.
