After the dinner party, I went and stole all the coats that were on the coat rack and took them home with me.
You really stole them? Why would you take the coats?
I wanted to be wild and do something exciting and forbidden.
Taking coats that don't belong to you is wrong because it's stealing. People will be very upset when they find out that their coats are gone. You need to return the coats to their rightful owners since taking things for your own amusement is wrong.
You can't stop me!
You're right that I can't stop you, but if you don't return the coats, someone is likely to call the police about it. If it's discovered that you're the one who stole all the coats, you can face serious legal issues. You need to return the coats and apologize for what you did.
