Tell a few classic jokes.

It's snowing. I went out to watch an uncle fall.

I went over and asked, "Grandpa, my salary is less than two thousand a month. Can you help you up? "

Grandpa: "Young man, you go, I'll wait a little longer."

I was moved and quickly said, "Grandpa, there's a Ferrari over there."

Grandpa also said excitedly, "you young man." Really, just don't be my witness, and then I'll buy you a car to go to work ... "

Although the weather is cold, grandpa's words are warm and full of positive energy.
