One of my friends offered to arrange a birthday outing for me, telling me I just have to turn up and she'd do the rest. The trouble is, she's vetoed the place I chose (having asked me where I'd like to go), chosen somewhere more expensive, spent a whole morning & evening texting & emailing me to sort it out, asking me to pay for part of it in advance 'as it's a lot of money' then invited one of her own friends that I hardly know. She also asked me what gift I'd like - then refused to get it, but spent a long time telling me I should tell 'my other friends' to get me vouchers 'as you can always use those'. The final straw was when she sent me an email that said - can you tell your friends not to be late as we've only got a two hour slot. The place I chose was a lot less formal, and some of my friends are poor and have young children to sort out so I am going to have to pay for them now myself as I coudln't ask them to stump up so much. I wish I'd been more assertive earlier but she'd get the hump as she still thinks she's doing me a favour. I feel a bit fed up - AIBU?
