Tell a joke to make me happy!

A child's paper is called Jiang. One day, his father was ill. Jiang wrote a letter to his father. Jiang can't write words were circled instead, the letter said

Dear old circle:

I heard you gave birth to a circle. I hope you can keep a good circle and don't just go on. Your son Jiang Xiaojuan.

After dad received the letter, he showed it to his neighbors. When the neighbors saw it, they thought the circle was an egg, so they read:

Dear old egg, I heard that you laid eggs. I hope you take care of your eggs and don't lay them casually. My father fainted after hearing this.
