Years ago, back in the 90s, my grandparents were about to fly to Italy for vacation. My aunt was dropping them off at the airport. Just as he's about to go through security, my grandfather stopped, turned to my aunt, told her to hold her hands out, and proceeded to empty his vest pockets of about a half-dozen unused shotgun shells. He then went through security and got on the plane. My aunt just stood there with her hands full of shotgun shells, wondering what her father was thinking.
