My brother totaled his truck when he was driving back from college a couple of months ago. He's now back home from school for the summer and takes my car everywhere (most times without asking me). His girlfriend is staying with us for the time being, and also has a car, but for some reason they can never take hers (which would be the logical thing to do, since when they take my car, I'm stranded because my parents both work and I have no access to another car).
Do I have a right to be a little annoyed? When it comes down to it, I really don't mind sharing, just so long as I don't have anywhere to go/he lets me know he's taking my car and I'll be stranded.
ETA: He must have caught wind of this post, because he just took it again without asking me. His girlfriend's car is in the driveway. Definitely hiding my keys when he gets home.
