The Importance of Calling on Parents' Anniversary

My family is pretty casual about that sort of stuff anyway. We do phone on birthdays if we remember. But it's not a guarantee. And there are no like presents or cards or flowers and things like that. I will be genuinely curious in the Reddit to see what the breakdown is of in families, whether or not calling on the parents' anniversary is the required day or the not required day. Because I feel like this one is the controversial day. It's like it's a romance day for them. Maybe your parents are having a little kiss and a cuddle on that day. And you don't want to think about your parents doing that.
