ticket or no ticket?

Okay .. .so I was planning to go with my friends to this festival we have every year .. we were going to go today. but friend#2 was busy. so we said” okay lets go on sunday” yea and we were all okay with it at first. Then friend # 1 says she doesnt want to go on a sunday and wants to go thursday. and she says its all friend#2’s fault for being busy . I know this is all crap but they got into a fight. and neither of them wanted to go anymore.I called twice to make sure that they didn’t want to go.. so I’m selling my ticket to my cousin. . now thats done. all of a sudden my 2 friends call me back and say they’ve talked it all out and have decided to go tomorrow.=( I have work tomorrow and both of them were just like “ your cousin can get her own ticket at the stand..blah blah blah. if I don’t go they are all not going and they are going to burn their tickets. what am I supposed to do now? I’m really confused ‘cause now they’re saying my cousin’s old enough to get her own ticket (19) and they will burn their ticket (WORTH 48 DOLLARS) if I’m not going. just talk some sense into me please.
