Words that can't be written are circled to show jokes.

One day, Xiaoming's grandfather was ill.

Xiao Ming wrote to his grandfather:

Dear oo: (Can't write, circle it)

I heard that you gave birth to O (you can't write when you are sick, ...)

I flew to see you with Fried O (chickens can't write, machines can't write, ...)

Your grandson, bastard (Ming Can can't write, ...)

When his grandfather received this letter, he read every letter as an egg.

Please read it again.

Sorry, it's a little long.
