You may have panicked when a friend asked, “Hey, can I throw these bags in your trunk?” Sure, you were happy enough to drive your pal to the airport—that’s what friends are for, after all. But open the trunk of your car? No way.
So you tell your pal, “Oh, go ahead and throw that in the back seat!” Underneath your cool exterior, you fear that moment when the jig is up, the party’s over. There is junk in the trunk (of your car) and just thinking about someone seeing it makes you feel nervous.
