this was just shared with me today: my sister’s mother-in-law wishes everyone happy birthday for everyone’s birthday. This may either be a Dutch tradition, an Indonesian tradition, a Dutch-Indonesian tradition, or just the mother-in-law in question. So she calls my sister on her husband’s birthday and says “Happy your husband’s birthday!”
I think this is awesome because I always want to say, “you, too!” when I’m wished a happy happy. I think we should propagate this tradition. In that vein, happy my birthday, everyone!
