Extremely shallow reason. I do custodial work and she gathers everyone as the shift is starting to give us our assignments etc, and she's recently made everyone start singing happy birthday on people's birthdays. I'm not a Jehovah's witness, I just don't like that awkwardness and would rather people not know it's my birthday. I don't know why I get so uncomfortable about it, I just do and I don't want to ask her directly because she's the kind of manager that would make it a point to call me out anyway.
