With my family, I've learnt there is no winner or loser. We all lose. By this I mean, with the passage of time, these arguments become irrelevant and we become more distant. I try my best to let bygones be bygones for the sake of not cutting off ties completely.
If it was me, I would rather spend time with my dog rather than difficult relatives. Over time, these relatives will outlive my dog. And they will forget. My dog doesnt care what I look like
