Story that ends in i have never found such a kind person ever since ​

I was traveling on a train where I fell asleep. someone stole my luggage in which I had money and other essentials. when the ticket checker arrived a lady paid my fine. she helped me a lot. when I told her about being robbed she helped me and took me to the police station and I found my bag. I insisted she take the money she paid for my fine but she said that in return you too help someone."I have never found such a kind person ever since."
