I can't imagine it will improve relations to mention you're not impressed with him "going" in the yard.
Think about it for a minute, and figure out what you want to achieve. Quick installation of pool, done well? No further issues with arguing over differing perspectives? Figure out what you want, then what wording will help you get it. Sweetonsno said it beautifully with regard to "managing" the toileting issue.
I think you're right. I need to decide how I want this to go and work backwards from there as to what to say,
The very first thing is scheduling the rest of the install.
He was kind of pushy about getting it done this weekend. I am constantly being told how busy he is and that if I want it done it has to be now.
So, I acquiesced on the timetable. It didn't really matter that much to me and there were a few positives.
The rest of the install cannot take place until after the missing parts arrive which is supposed to be Wednesday. He said he would plan on doing the rest on Thursday but it might be rainy that day so then he says he will come the day after.
I want him to wait until the weekend or after. Because he made such a huge mess in the backyard and refuses to clean it up, I have to have someone come in and fix things before the pool is erected.
(He kept telling me that he would grade the piles of dirt that he was piling up all over the yard but then he just left it there. He also drove the machine over my concrete patio and cracked the corner right off!)
So, the very next issue I will have with him is that he will want to come when he wants to come and not at a time that is agreeable to both of us.
I'm not very good at being proactive so I will use some version of Sweet's script to address all the issues including the peeing, that I think will come up.
