Plz someone tell me!!!!!!!!!!!!!!!! plz!!!!?

Maybe he forgets to close the chat application when he goes to bed? Sometimes I leave my messenger on and forget about it. One of my friends messaged me a while ago, and I never responded. It wasn't on purpose. I was just not by the computer at the time. Why don't you ask him why he's still online so late? That's probably the reason but you might as well ask him or you'll probably keep wondering.
