I told my friend that I was going to the vans warped tour on the 20th. so he could go with me, he also bought his for the 20th. I finally looked at my ticket and realized it was for the 21st not the 20th. can we change his ticket? please say yes. I really want him to go with me and if not then it was a wate of $40 for him. HELP!!!!! I will love you forever
