birthday threshold

The level of friendship you deem necessary to exist between you and a friend to warrant posting on their wall when Facebook alerts you it is in fact their birthday.

Wife: Hey, honey, did you wish my cousin Jay a "Happy Birthday" on Facebook?
Husband: God no. Jay is like you're third cousin which makes him NOTHING to me. Not even sure how we are friends on Facebook. Never met the guy.
Wife: That's not important, you know Jay was there for me when my parents were going through that thing when were kids.
Husband: Sorry. Not happening. Jay is beneath the birthday threshold.
Wife: Fuck you.
Husband: Rules are rules.
