I have completely checked out of work, so...
This has been the subject of many an arguement bewteen BF and I. I absolutely hate it when he drives my car, especially when I'm in the passenger's seat. It makes me uncomfortable to see someone else driving, but most of the time he insists on it because I have the better gas mileage and because he "hates" the way I drive (which, of course, I take offense to).
I am comfortable in my car. I spend a lot of time in it. It's small and I'm very short (under 5'), so everything is very specifically adjusted. BF is over a foot taller than me, and he readjusts everything, from the mirrors to the steering wheel. It takes me forever to put it back the way that's comfortable for me.
My mom once overheard us arguing and said, "What's the big deal? It's just a car!" I likened it to someone borrowing my underwear - it's just not the same once you know another person's been in it.
So - does BF/FI/FBD drive your car? Do you let him? How do you feel about it? Am I the only one who's crazy possessive of her car?
