My friend bought tickets for her and her boyfriend to attend a concert, however, he can no longer make it.
My friend has now asked me if I want to go instead. She is really keen for me to go as she is unable to find anyone else and will lose the money of the ticket if I don't go.
I have said yes, but have said I won't pay for the ticket. I don't see why I should when she's only asking me because she has no one else and she'll lose the money from the ticket anyway as her boyfriend can't make it.
My friend is now really annoyed and said I'm a bad friend. AIBU?
