The first quality is honesty and credit. I think this passerby is really honest and trustworthy. He is honest and knows that the money is very important. For others, the money may be equivalent to living expenses. It is impossible to take other people's money, and he will not be greedy for this petty gain. He is really honest and won't let himself do dishonest things. I think his quality is really good and worth learning.
The second quality is kindness. I think this passerby is really kind, because after he found this pension, he didn't take it for himself, but waited for someone else to claim it on the road. This is very kind, and he can make himself do some kind things, which is really beautiful for others.
The third quality is warmth. I think his quality is really warm, because he can tell us to be honest and trustworthy with such behavior, not greedy and cheap, very warm, which makes many people feel warm and good.
In a word, I see many excellent qualities from him.
