First dates are difficult since you know very little about the other person. You may know a few things about him or her based on previous information. Instead of talking about the weather or school which is very traditional, I would start talking about the things you have in common. It may be hobbies, careers, or other interests. If you don’t know anything about the other person because maybe it was a blind date,
I would start talking about topics that interest you and listen to see if the other person is also interested in those things. This would allow you to pick up on the things that you have in common with him or her. Once you figure out what you have in common, it would be best to spend time talking about those topics.
