Going to a wedding tomorrow. the bride is a friend from work, and quite a few poeple from work are going, including my best friend and her partner - lets call them A&B.
DD & I will be travelling up to the wedding by train, and have a group ticket with A&B. It's the kind that you have to all travel together on, and is heavily discounted (but still quite pricey for me).
Another colleague has offered me & DD a lift back, which I've jumped at, as the prospect of a 3 hour train journey, including going across London by tube, at night, with a 7 year old, is not a particularly appealing one. A&B knew this when we booked that tickets and were understanding and absolutely fine about it.
Another colleague - let's call him C - is getting a lift to the wedding, but would like to get the train back. He, like me, is not particularly well off, and it seemed to make perfect sense for him to have the return portion of my ticket, which he will pay me for, thus saving us both money.
Now the tricky bit: A really doesn't like C at all. I sent her an email earlier, clarifying the arrangments, and saying "by the way, sorry about this but, C might be joining you on the way back..." and explaining why.
She has sent me a quite clipped one line response - not mentioning C or the return journey, but I just know she is really bloody annoyed with me. I imagine she will be quite frosty tomorrow.
So, AIBU? Is she? What should I do / have done?
