This morning, before I left for the airport, I had hurt my back. And I could 1 lift my bag off the floor, let alone 2 it into the overhead locker. Luckily, one of the flight attendants put it along with two cases for me.
At that time, a man 3 in front of me must have noticed that I was asking for 4 . When the plane 5 , he instantly stood up and got my bag down. He also 6 to carry one of my cases down the 7 . And then he waited at the bottom of the stairs for me to 8 to get my bag.
A lady walking beside me carried my other case full of things for me. It was obviously 9 for her, but she managed it. She seemed not to want her kindness to be 10 , so I silently accepted it. Then I saw her again at the carousel（行李传送带）, and she took my bag off the 11 .
I would have managed to do all of these things on my own, but these well-meaning humans sensed that I needed help and just 12 in without me needing to ask. It was one of the most 13 experience I had ever had. I couldn't feel 14 enough to those persons who had taken time out of their lives for a（n） 15 . I was so appreciative of their kindness that I would remember it forever.
