I can't remember if this was mentioned earlier in your thread (I am really getting everyone's threads mixed up now) - do you have a DB coach? I'm curious what a vet or coach would say about your opinion that giving H space leads to him taking more space
As far as your H there to mow the lawn today, you said he didn't say hello or goodbye but did he know you were there if you didn't go down to see him? Maybe he thought you were out?
I think it would be good for you to set a boundary with H. Some other recent threads have discussed how to do that. If I see one I'll paste it in here.
