Is that why we drive on a parkway and park in a driveway?
Lily Tomlin used to observe that we go to a store to buy a small garbage pail and put it in a paper or plastic bag to take it home. Once we get it home, we put the bag in the can. Why? she asked...
For some unexplainable reason, this also reminds me of an old question Steven Wright iirc used to ask: Why do we have names for the soles of our feet but not the tops?
I'll stop now (fortunately).
