I had a good chat with a girl last night. As a result, she sent a message at night, and I didn't reply until 7 am.

If you know the nature of her job in advance, you can understand, but if you know the nature of her job or say that she has no job and has a lot of time, she won't reply to you. First of all, you were not happy when we talked last night. Second, you are a little impatient. The more you do this, the more she feels that she attaches great importance to it. Sometimes she needs to keep her appetite, you know. The most important thing is that you send a message. Don't wait too long. There are still many people waiting for you in the world. Why bother?
