Her entire existence is public. Which makes it very obvious when something hasn’t been shared. Besides, it’s a part of influeza culture to beg for birthday wishes for their partners.I have to be honest- I don’t like this habit of people doing all these things publicly. I don’t feel there us anything off because she didn’t do it in her stories. Yes- she is the one that does all these things the way she does- but maybe she just decided to do this one in privacy. And then when people re- share who said happy Bday to them- so weird.
