Why do men always send me messages late at night?

It's definitely not a good thing for men to send you messages late at night. Either he wants to ask you out at night. It's been a long night. He feels lonely and empty, so he wants to ask you out. It is obvious what to do. If something happens to him, in general, people rarely send messages late at night. Unless something happens or something happens, he will send you a message in such a hurry.

Either his work is not smooth, or something bad happens in his life, so he talks to someone. So even in the middle of the night, he came to you, and in the end, he probably wanted to tell you. Late at night is the most tiring time. If he gives you a white message, you may agree in a daze and so on.
