Why does he interject but he can't respond to a simple message?

I'm friends with this guy but I'm kind of angry with him right now. He has on his iPhone a thing that shows when he READ a text message. We had texted and my last one he left unread! He didn't even freaking read it.what'd he do delete it? And the same thing happened with facebook - facebook says when the person read the message, if at all. He never even looked at my last message. WTF?

well then i wrote something in this comment thread and i guess he just had to interject. He wrote a comment right after mine, addressing me, tagging me, saying something directed at me.

I don't get it. How could someone not even look at a a message somebody sent them, on TWO different avenues, and then stick his nose where it doesn't belong and address that same person. I just don't get it.

There's no law that says you have to read a text or facebook message.
if you always go on like this I probably wouldn't bother to read your messages either.
