when you are with friends and one of them says he'll drive you home there is a natural order in which way he is expected to drop people off. If he cannot drive and drop people off in a timesaving manner (person A's house is on his way to person B's house) he will always drop off first the person he likes the least. In consequence the person he likes the best will be driven home last. This rule or law, if you will, has the affect that the best friend or in some cases the romantic interest will always be driven home/dropped off at the end of the whole dropping procedure.
Now why am I waisting valuble time explaining this extremely simple rule that everybody has long since grasped?!?!
