I've Nc for this but I'm a regular poster.
It was my birthday on 10 January. I have a friend who I've known for six years. We see each other at least once every 2 months, normally in a group setting with other friends.
She hasn't wished me Happy Birthday. No card, no text, no Facebook post (even though other mutual friends have so she would have seen it). She's got a busy life. So have I. I've always sent her at least a card. No falling out or anything. Last time I saw her, all was fine.
First world problem I know, but I feel a bit hurt about this. AIBU?
