Okay, you know how people always type something to you. Then, all of a sudden, you somewhat misunderstand them. They reply: "Didn't you hear what I just said?" The next time this happens to you reply: "How can I hear you?! This is internet dammit!", or "All I hear is the bang bang bang of my keyboard and the annoying sounds from MSN." Seriously. This online "Hearing" business has got to stop.
Humans have evolved enough to "hear" through the internet. We can also see someone "talk" through text on a screen.
Sadly, he did get the point. People do say that stuff all the time as if you are standing right by them but you can't 'hear' someone obviously with what you said, and you can't 'talk' on text messaging either. It is ironic though, how many people say those sorts of things. I usually tease and say something lame back and they get annoyed. xD
