The context of the following conversation is Bailey told about the time they got arrested in order to scare the kids a little so they would behave.:
Bailey says The kids were being horrible the other night, so I told them about the time I got arrested..
The friend responds I didn't know you'd been arrested.  What was it for?.
Bailey responds Oh, a friend and I  borrowed a scooter without permission when I was 15.  We got caught and I had to go to the police station.  Since I was a juvenile and didn't have a record, I didn't get in too much trouble..
The friend responds I suppose that made an impression on you..
Bailey responds Well, let's just say I never borrowed anything without permission after that.  I think I scared the kids when I told them about it..
The friend responds Hopefully you did and they won't repeat your mistake..
