Agreed, I seem to loose a friend every time I am asked to borrow money or for a ride somewhere. I just feel like bad saying No. I have no real good reason other then its mine, walk or catch a cab or work harder and buy a car. There offer for paying gas money is just annoying since I don't need there money nor do I want to drive them anywhere or just drop them off anywhere. What's worse is when I am about to head out and my roommate asks me where I am going and then asks, can you drop me off here.
I find if you do give someone a lift, its like feeding a dog off your plate.. even one time will result in a mooch and they will continue to ask. Even though I drive around aimlessly a lot, doesn't mean I want to drive you somewhere.
Like what if I hit a pot hole and bend my rim or get a flat tire, a speeding ticket or an accident? Rock hits the windshield, anything.. If I was going somewhere and something happened well I will deal with it. If I am driving someone somewhere and something happens that could have been avoided because I simply wouldn't be in that place at that time I would be upset
