When Mark first arrived in Thailand, he saw an old man selling something cheap in the street of Chiang Mai. The old man was one of the poor people in Chiang Mai and there was no (different) from beggars (乞丐). Most of them were some lonely old people. Their life was very hard.

    Mark was a kind man, so he gave some change to him  thinking. The old man told him to pick something he likes. Mark didn't choose (something) and left.

    But the old man followed him (close). At first, Mark didn't think a lot, just supposing he wanted to go home. But when he went out very far and saw the old man still following him, he was a bit tired, (think) the old man must feel he was kind and wanted to beg more money from him.

    Mark turned back and told him not to follow him he hadn't much money. But the old man seemed not to understand what he (mean), still following him. The bag on his back made him sweat(流汗) all over.

    Mark happened (meet) his Thai colleague (同事) in the street and his colleague heard this. The colleague turned to ask why the old man was following his friend.

    The old man said out of breath, "My son, you gave me money, but didn't want my things. I see you are a foreigner. I just want to follow you and show you the way. I can do for you is this."

    Mark was shocked. He said he didn't know why, when he felt the old man was just his father.
