I'm going to take my friend's lighter and throw it away
Why do you want to throw it away?
I want to mess with him.
It's not cool to throw away your items that belong to friends without them knowing. It cost them money and it will waste their time looking for it.
My friend is a jerk, I didn't care about him anyways.
Even if he acted like a jerk you should tell them what was wrong. Not ruin your friendship, you may regret doing this.
