I'm going to dump several pounds of dogshit on my neighbor's lawn while they are away.
Is there a reason why you want to dump several pounds of dogshit on your neighbor's lawn?
He is always antagonizing me with irrational things.
You need to treat you neighbor and their property with respect. Two wrongs don't make a right. Therefore, you should just talk to him instead of doing something bad which can get you arrested.
I have a better idea why don't I distract him from his family and life, give him a fucking stroke.
You just need to learn to ignore your neighbor and stop getting into arguments with them. Doing something like that is gross and immature.
