Father

 I was at the park today earning my 10K bonus steps for the day. 

I was passing by a family---a father, his son, and a baby girl on a stroller.

"Father! Father!" A boy with beautiful wavy hair, about 8 years old, tried to catch the attention of his father who was 5 meters away. 

"Father, pass the ball!" I think he was referring to the football under the stroller. 

I honestly thought the boy was joking.

Irritated, the father answered "Don't call me that!"

I slowed down because I wanted to hear more. 

The boy looked down while slightly leaning on a park bench. 

I saw the father walking towards the boy, and he said...

"Call me dad!"
