You shouldn't get into trouble.
Katy is a huge fan of a rock group that will be coming to town for a show over the next weekend.
Katy wants to meet the guitarist for the band and get his autograph.
Katy contacts the band's media representative and finds out they will be signing autographs and meeting fans before the concert.
Katy stakes out the hotel where the band is playing and breaks into the guitarist's room while he's out, to wait for him.
Katie gets to talk to the entire band and the guitarist signs a picture just for her.
Katy never gets to meet him, and he never signs anything for her because he calls the police to complain about her behavior.
