to be pissed off at someone claiming it's their birthday every single day on facebook?

[othermother]

A "friend" is having birthdays almost every single day. Am I right to be feeling jealous?

No, you have no sense of fun.
What harm are they actually doing?
My mate had a birthday every Thursday once he'd been diagnosed with leukemia. He made it to 51 that way, instead of a measely 19.

Just think of how old this friend must be by now. For example if s/he did it every day for a year then that's 365 birthdays in a year - and I was feeling old!! Lol
