It's a fairly straightforward situation, but I fear will be a long story, I'll keep it as brief as I can.
Several months ago some friends planned a trip abroad to celebrate a birthday and go to a special event. I originally said I couldn't go because I couldn't get the time off work, but I've since changed my job and now I could.
Once I realised I could go, I persuaded another friend to cone with me, she's a nice friend but not really part of the original group. We'd have had to arrange separate accommodation, as theirs was full. Anyway we dithered until the special event was sold out, so that was that.
Now, one of the original group has dropped outdue to illness and they've asked me to fill the spot. I'd love to go but I feel bad for the friend who agreed to come to keep me company/share my costs, I know she'd love to go too....
WWYD?
