Why do boys always reply to messages in the middle of the night?

Boys don't reply to you at night and reply to you the next day. There are generally three situations.

First of all, I am too busy at night. I don't have time to read WeChat and mobile phone. I don't care at all. I'll get back to you the next day when I find it.

Secondly, I saw it and didn't want to reply. I had something important, or I was with other girls and didn't want you to know, so I didn't reply.

Finally, this boy is particularly annoyed with you and doesn't care about you at all, but he thought about it the next day and felt that he didn't want to offend you, so he reluctantly replied to you.

I hope you can know the real reason of this boy according to the specific situation.
