28．I was working one night when a couple came in.They picked a quiet corner and sat down without much energy.And I thought both of them were in need of a shower and a change of clean clothes.
I served them food and then focused on my own things，but I was still concerned about them.They looked really sad.The woman explained in the end.They were worried about their little boy who was sick.They had been in the hospital for many days and the nurses asked them to rest for a while.
I felt terribly sorry for them.I still remembered exactly what happened to my little daughter one year before.I understood their struggles and pains more than others.The nurses had done the same thing to me.And I had been forced to be away for a few hours.
I knew there was no way to reduce their anxiety.but I could help them a little.So I told them that the meal was free of charge that night and provided them with delicious desserts they hadn't ordered before.I wished them luck before they left.To my surprise，a few minutes later，the young woman came back.She told me that she and her husband were really grateful for my kindness.Then she handed me a few flowers.
A few years passed.One day I was approached by a woman and she said， "You probably don't remember me!" Beside her was a little boy who was playing on the street.
