I can only guess and am left to wonder at your generosity and what motivated you to send a flight attendant back and offer to trade your first-class seat with me so I could sit with my husband. I assume you saw me pause at his seat as I went by, to chat and kiss his forehead. I noted your warm smile and the twinkle in your eye as I came forward. I gave you a hug to thank you and you said, “Just enjoy the time you have together.”
