He's not being a tightass about it at all. Does it still happen? If so I would put all their shit on her doorstep. I don't care about "sinking down to their level." She deserves it.

What pissed me off most about that story is when he asked her not to do it, she said that shit back to him. It doesn't matter if she thinks it's good for the lawn or if in her opinion it's just grass; it's his fucking lawn! If he doesn't want dog shit on his lawn, it doesn't matter if it's good for that lawn or not, you stop shitting on his lawn.
