Is OTHER wrong in the post ? POST : I have a friend that was going to buy four concert tickets for a group of us.  She was supposed to buy them several weeks before the event. Everytime I followed up with her (did you buy them yet? How much do I owe you?) She had not purchased them and just kept saying she would get to it.

The day before the event she messaged me , "hey, are you still coming?". Me, "um I haven't heard back from you so I made other plans." Her, "oh yeah, I forgot to tell you that I got the tickets". So at this point I cannot go but I tell her that since I did tell her to get me a ticket I would still give her the money. Approx $75. 

She says she will try to find someone else to take it so I won't have to pay. Ok that would be fine. 

About an hour before the event she messaged me "Ok,  I am going to ask a friend of mine if she wants to go. She can’t afford to buy it but at least it won’t be wasted. She has 6 boys. "

Now she expects me to give her the money for it. I can see not wanting to "waste" the ticket.  But AITA for feeling like if she wanted her other friend to go then she should pay for it?
