She gets there and forgets her ticket to get in.
What was her reaction when she found out that she had no ticket?
She said she didn't understand how she forgot it at home.
Concerts are fun if you bring your ticket with you to get in. Everyone needs to bring their ticket, so keep it in a safe place so you never forget where it is. Otherwise you wouldn't be let in to see their favorite band!
Eh, you can always just sneak in if you don't have a ticket. There's no reason to pay if you don't want to.
Well, it's not really fair to sneak into shows without paying. This is how those people make their living. Besides, you might get caught and get arrested...just pay for the ticket and enjoy the show!
