A man who can't drink or smoke is not a real man?

They are not laughing at you. In fact, when friends are together, they have the same hobbies or "similar tastes". They will, but you won't, and you may feel that you are "out of touch with the masses". They want you to advance and retreat with them. In fact, smoking and drinking all need company, and a person's alcohol and tobacco are more lonely. In fact, it's a society, and these things must be learned a little.
