Dialogue about a Party

Hi! We haven’t seen each other for a while. I am very glad to see you again! I want to know what you have been doing in this time, but first I want to tell you something. Do you know Mary organized the party last week? Party was in her village, I was there.
Yes, I knew about the party! She invited me, but my parents forbade me to go. I was very angry about that! I think my parents are only thinking about themselves.
Sometimes I have problems with my parents too. Mary’s party was great as always, but now she is in trouble. She organized the party while her parents weren’t at home and the neighbours called police.
I can’t believe! I think she felt very disappointed. Why the neighbors called police?…
