Another: just quick update. Took your suggestion to heart. H sent me a text telling me he would leave me a check in morning. I ask if he finished mulching job. He answered nope, got to go back in morning. I just said, don't forget your cell # is released and you have truck insurance info. I'd shop around if it was me. Was that a nice reminder - I wasn't telling him what to do and wasn't telling him I was cutting him off. Just reminding him it was there to do.
Good, now don't mention it again. You've informed him and it's up to him to take responsibility for it. If he doesn't, well you're not his mother, he needs to do grown-up stuff on his own now
