Here is a good life lesson.
If your mother kindly let's you borrow her car, then after graciously returning the car try not to stuff HER keys back in YOUR purse. This will most definitely avoid a situation where you drive an hour back to your house only to get a phone call from mom inquiring about said keys and then you have to mail them back which will cost you $6.24.
Just a tip I thought I'd share.
Not that that's happened today.
Is it Friday yet?
