I decided to play a prank on my neighbor and I locked him in the barn last night.
You locked him in there and left him in that barn all night? You're kidding, right?
No, I left him in there. I thought it would be funny, even if he freezes to death.
Holding him in the barn is borderline kidnapping and you outright admitted you wanted him to die in there. You should pray he doesn't go to the police to press charges against you.
Do you think I would actually let him die in there? Lighten up, it's just a joke.
I think you should pull a prank that your neighbor might actually be able to enjoy with you. Locking him in a barn all night would not be very funny for him and he could have you arrested.
