I cut down the neighbors tree because it looked rather ugly
Did you get their permission before cutting down the tree?
No, but they never watered it and I didn't see any fruit.
It was wrong of you to cut down your neighbor's tree without their permission. It's illegal to go onto your neighbor's property and remove things.
Oh well it's too late now.
You should go and apologize for doing that, I'm sure your neighbors must be mad you cut down their tree.
