So probably for the adults amongst us its definitely embarrassing.
I've been in a training group for the last 8 weeks and we went out for drinks on Friday - 3 in the training group and the trainer.
I made an in joke about him accepting our friend requests on FB - no one had added him but this was a relevant and very in joke.
Today both the people I was out with mentioned that the trainer added them on FB .... and he didn't add me. He knows I have FB.
It's not a FB thing ... I think its just the message that he clearly doesn't like me.
