In college I had a part-time job at a shop downtown that sold doughnuts(a kind of cake) and coffee. The small shop,  36   on a block where a dozen buses stopped, it provided food to people who had a few minutes to wait for their  37  .
I  38  coffee in takeout cups and patiently waited on customers who’d point through the glass case and say, “No, not that one, the one two rows over.”
Every afternoon around four o’clock, a group of school children would burst   39  the  shop. Adults would glance in, see the crowd and   40  on. I didn’t   41  if the kids waited for the bus in the shop.
I came to know them pretty well. The girls would talk about school. The boys were more quiet, choosing not to   42    their secrets, but still, they’d wait every day in the store   43  their bus came.
Sometimes I'd hand out bus fare （车费） when a ticket went  44  — always repaid the next day．When ii snowed, the kids and I would wait  45  for a very late bus．They'd call their parents to let them know they were okay．At _ closing time I wouldn't  46  the door, and the kids and I would wait in the warm store until their bus finally arrived．

"I want you know I appreciate what you do for my children．I  51  about them having to take two buses to get home．It  52   a lot that they can wait here and you are keeping an eye on them．"
I told him it wasn't a big  53  ．that I enjoyed the kids．
"No, you don't understand．When they're with the doughnuts lady, I know they're  54  ．It is a big deal．And I'm grateful．"
