Write an interesting short story that ends with i have never found such a kind person ever since​

Today is a sunny day, I walk out my house and I saw a little boy was playing with his dog, I see that a mam is hide behind the grass, I'm not sure what he he is doing, but I think he want to do some bad things. So I walk to my back yard to hide my self to get closer, as I open the back yard door, I walk quietly, and don't let that man and the boy notice me, as I drew closer, I'm sure that he want to do bad things, because he looks like he want to steal the things on the chair that the boy put down, so I grab a rock and throw it to him to not let him to steal things. As the rock hit him, he got knock to the ground, when he get up, he was dirty and some poop on his body, I feel embarrassed, the man look at me as he wear up his pants, the boy rush to the man and ask him what happen, the man said somethings, and I found out that the man is the boy's father, he was pooping behind the grass, and they got lock out, because they forgot to take the key, they need to wait to the night and his mother back to get in. Then the man walk to me and said, "I have never found such a kind person ever since​!" Then he grab a rock throw it to me just like I throw to him.
