Bought festival tickets with two friends. They don't know each other. One friend now can't go and neither can I due to circumstances we can't control. I feel really bad dropping out and leaving my friend. AIBU to gift them the two tickets (other friend hadn't given the money yet) so they can try to get someone else to go with them? Or is that unfair as they may not find anyone and I should pay for their ticket so they aren't out of pocket?
