I used to always ride in the back of my mother's car, until my dad made fun of me for doing that; why, at my age (I was younger than I am now but still an adult), was I still riding in the back like a little kid? ;_; So I started riding in the front seat.
I now rather prefer it because it's just more comfortable for me (I can barely get a back-seat seatbelt on anymore, they're so damn cramped!--plus if the car is full, I'm wedged in there with at least two other people
), and it's kind of awkward to be in the back seat if I want to be talking to her. If somebody unfamiliar is driving, well...I might feel like I'd be more comfortable in the back seat, but then I'd feel like they might think I'm snubbing them, and I'd feel rude, so... :/
I guess I just sit wherever the other people in the car want me to sit. Even if I don't really want to sit there.
One thing though, I REFUSE to sit in the middle of the back seat.
I must have an escape route open!
Fortunately situations like this don't come up too often...I don't go out much. :/
