Chivalry

As I was leaving a store today with a heavy carpet runner on one shoulder and a large ceramic pot in the other hand, a kind gentleman noticed. He offered to take the pot and carry it to my car for me.
Although that would have been helpful, I declined, "That's OK. I got it!" "Are you sure?" "Yes, thank you so much!"
Later I wondered why I didn't just let him.
Instead I followed behind him muttering what I construed as encouraging words about the glories of chivalry.
