I was taken to the police station as a teenager
Why did they take you to the police station?
I got arrested for robbery.
It's understandable that kids cause mischief and break rules from time to time, but robbery is a serious offense.  It's not okay to do things that are illegal and that can harm others, so the police were right to arrest you for it.
I was joking.
Well if you are lying you know you make people question everything you say. Nobody likes someone who lies about serious things.
