Overreaction? I might call the cops on him...Tiny update in comments
I asked my dad for his help with my car because the A/C started to defult. My brother loves to mess with stuff so he decided to jump in and try and help. That's fine when he has supervision around because he often has a mean streak that likes to screw things up on purpose when he's bored and wants attention (he's mentally ill)
They got the car to start cooling off again, yay. He comes up to me while I'm by myself and tells me if I give him $40, he'll get a part for it to help it cool down even more. I told him no thank you and go to hang out with mom. He comes over and starts telling mom, right in front of me, that he's going to need the car to cash a check so that he can buy this part for my car and I'll pay him back later. I tell him "No, I already told you no, now drop it." He batters back and forth with mom about going to get this part (literally 6 times after we've told him no.) He finally says "Okay well, I'll just go cash the check then and come back.." After mom threatens to give him some house work to do if he was bored.
Now I know my brother doesn't just let things go this easy...he's shown that much before (on the day of my sister's babyshower when he flooded the kitchen trying to "fix the pipes" after mom already told him not to touch it).
I'm worried he'll try and "fix" my car the way he "fixed" things in the past, especially with how persistant he was being after we told him no so many times and to not even think about touching my car.
So much so that if he does go along with it, DF says to call the cops on him to let him know just how serious we are.
Now I don't know if that's an overreaction or not...so let me ask y'all what you would do if this was your situation and he tried interfering with your car after the multiple "NO's" ?
