there is a saying in my family (and I am sure lots of other peoples') that is
don't let them know where your goat is tied up
kind of like
don't let people see where you buttons are sort of thing
i think that your husband knows what buttons to push to get a reaction from you
you loan out the truck you are strong and tell him you can't possibly get it now because youa re at work he threatens you and shows anger (maybe your goat is here...you don't like confrontation or you are afraid or intimidated by anger) you get nervous he gets to feel powerful
I am suggesting you move that goat when he makes a totally empty, clearly not in reality sort of threat (there is no way a sheriff would point a guna t someone and demand a truck be returned...unless they are a felon and armed and dangerous...it isn't grand theft auto...he is trying to intimidate you) you simply state i am sorry you are upset about that i will get the truck back to you asap
when he keeps making demands simply state once again, i am sorry you are upset but I really have to go back to work have a lovely day goodbye
move yoru goat
he will see that intimidating you doesn't work and will have to try to find a different way to get his way
