One of the magazine stands outside the airport security had flowers for sale. I told the ______ that

I’d like to buy flowers for someone else, and she could decide who to ______ them to. She looked a little ______, so I explained perhaps she could hand the smile cards with the flowers to someone who seem to need some to ______. At first, the clerk ______, "That’s strange." Or maybe, "That’s crazy." I can’t ______ which. But then, I explained a little more about the ______ card and the concept (概念)of doing

something kind for a complete ______, and she brightened up.

"I’ll never know how it turns out," I said," but you will have the ______ to make someone’s day." At that point, she started to seem ______ excited about it.

She went to take the ______out of the water. Then I explained, "It’s fine to ______them there until the person you want to give them to ______."

At that point, I thought she was somewhere between amazement and delight, as it was ______ that this was really not a ______she had ever gotten from a customer before.
