I know what noise is, who doesn't.
I have no idea what you're talking about in relation to your joke with Renter ;. That, however, is irrelevant. You were cheating this morning and everyone who has seen the demo agrees with me.
On chatbox your excuse for killing these people with your wallhack *ahem* sorry... skill... is because of your sound system. CS on a soundsystem is completely rubbish, that is why every professional gamer uses headphones. The clarity of sound is better, and directional sound is better. All of this is irrelevant, because the Terrorist you awped instantly at mid alleyway didn't make a noise, or fire. So saying it was sound that made you shoot him is a complete and utter lie.
