Why does he only text me at night?

Anonymous
This guy I've been texting only texts me at like around 10 or 11 pm. I've noticed he's like barely ever on his phone when I see him in person and in class but he is on it every now and then, but even if I were to text him earlier that day he wouldn't text me back until at least 10 or 11 and when he does he answers back immediately until one of us says goodnight and it's not like it's dirty like he doesn't ask for pictures or anything it's just confusing and frustrating I have to wait till night for a text. So what could be reasons he does this?
