To think I should have been invited?

[CrohnicallyPregnant]

Briefly, I'm off on maternity leave, work had a leaving do for someone and the first I heard of it was when I saw pictures on Facebook. I mean, I wouldn't have wanted to leave LO to go, but given that I'm in touch with a lot of them on Facebook and several people have my mobile number, I think they should have mentioned it so I could sign the card, contribute to the present etc.

WIBU to mention it?

Are you the one who contacts people off work for do's OP? If you try to include the absent then yes it's a bit off they didn't ask.

Definitely don't say anything, you wouldn't have gone anyway so what's the point?!
