I get so used to checking the Facebook birthday notifications every day, it messes with me when there aren’t any. Once you have a certain number of friends, it seems like there’s at least one a day. Every once and a while there isn’t any for a day, though not often, and I get skeptical. I actually have to go checking, because sometimes Facebook just messes up and doesn’t show the notification.
It just seems like an odd thing to get paranoid about.
