Joke: What are you gesticulating about?

Joke: What are you making blind gestures

A classmate went to Africa to aid construction. The construction worker who just arrived at the construction site to receive him was a black man. He communicated with others in English, and black people did not make a sound. Then he spoke in French again, but the black man still didn't speak. Then he gestured with his hands. The black man finally spoke: What are you making blind gestures for? I was tanned, and the whole construction site was full of Chinese people.
