The best dad in the world

"You know? Grandpa,
It turns out that Xiaoda’s father is a doctor! "
"Really? Xiaoda's father is awesome!
It’s so uncomfortable to be sick, but luckily the doctor can treat you. "
"Well grandpa, if all dads are doctors,
Isn't it super awesome? "

can you? Will it be so?
Think about it, if the streets were filled with doctors hanging earphones and holding syringes...
Wow! This is too terrible!

Right? Instead of being a doctor, you can also be a driver, chef, firefighter...
You can also be a cosmic superman!
"But grandpa, what kind of father is the best and the best in the world?"
