My male colleague said that I was not gentle at all, and I was still laughing. Why did he say that? Am I really not gentle? Although it is indeed a man. He snickered?

Actually, you don't have to pay attention to what he said. Actually, it's just boring to joke with you at work and laugh at you. Even if he really says so, you don't have to pay attention to it. He is not your husband or boyfriend. Why be gentle with him?

He is actually making fun of you. Just ignore such people in the future. Not someone you care about. No matter what he says, the more you care about him, the more you will make fun of you. Do you care if everyone says that you are not good at this and that? So anyway, just be yourself. You will always meet people who understand you.
