How can you make a girl laugh?

It takes time to make her laugh. First of all, a girl doesn't know you, so even if your jokes are funny, she may not agree with you. On the contrary, if that girl knows you well, she will laugh at your cold jokes.

I suggest that you talk about familiar people and things first, preferably things she knows, and then talk about her hobbies, so that she will naturally be willing to talk to you if she is interested, so that you will gradually get acquainted, and you will not feel nervous when talking about humorous things.
