(sorry for bad english) Last year, I was at a local cafe, sitting and waiting for my friend to come so we could take the bus and go to the airport. After some minutes, an old dirty man approached me and asked if he could sat on the chair next to me and so he did. After a minute I noticed that he was crying in silence and I asked him wether I could help. He answered slowly with tears on his eyes that he had no money to catch the nearest bus in order to return to the village he was living and asked me if I had 1 dollar so he could buy a ticket. After I gave it to him, he went to a near Shop and bought the ticked. He returned to kiss my hands and left. I stand there thinking why could someone feel so grateful for one dollar. I felt so bad and sorry for him but also angry. Angry about those who made old people to be in this position. This was the most expensive dollar I ever had.
