Or my mother is trying to force me to make a decision I don't (or don't think I should have to) make:
Background: I am currently living at home (in Massachusetts) with my mother, brother, and there are two cars in the household. My car which was brought with my college funds, (but my mother is currently helping me maintain until I get a job), and my mom's car. My brother doesn't have a car, and relies on my mother for rides or borrowing her car. He isn't aloud to touch my car because we have had issues in the past. The three most prominent of which are leaving an illegal drug in a car we once shared that I was driving at the time, recently taking my car without asking (it was I woke up to discover my car wasn't in the driveway situation), and I don't like his driving. He has an app on his phone that tracks police cars and he spends more time paying attention to that than actually driving.
My aunt invited me and my mom to her house on Cape Cod next weekend. A Saturday to Sunday trip. My mom wants me to leave my car home alone with my brother. Normally that would be fine if I got along with him, but he also goes into Boston every Friday to spend the weekend with his girlfriend. He is always driven and doesn't come home until later afternoon or even during the evening on Sunday. I don't want to even give him the option of borrowing my car because of his history and his regular schedule. Normally he wouldn't need it. If I give him the option he will take it because he is just that kind of person. For some reason my mom is trying to force me to make a decision. Either let my brother borrow my car or don't go down to the Cape for the weekend. I really want to go, but I just can't trust him. Any suggestions on ways I can convey to my mom she is putting unfair pressure on me. If my brother was going to be stuck out in the suburbs without a car then I would say yes he can borrow it. He is not though, and I don't want to give him the option of borrowing it either.
