I think I might be the mooch, not on purpose (though when I lived in my car eons ago, maybe)
But here's the thing, I ask for a ride, I offer (or leave in the car) gas money. I ask to borrow a thing I offer 'rent'. but no one ever asks for a ride off me, or to borrow anything. (I try to return item with baked goods instead)
Part of it is I haven't anything interesting to borrow
.
So the next time you think you might have a mooch, do ask them for something they are capable of. Don't ask for an expensive evening dress if the only time you have seen them in one is your own. instead ask to skip dinner out when they stop by for the ride.
Also sometimes consider if paying there way makes the meal better than eating alone. I used to pay for a fellow because I knew he couldn't afford it and I didn't want to skip meals out just cause I couldn't find a proper 'sugar daddy'.
