Right.

Lemme tell ya, if I THINK that there's an enemy hidden somewhere, I'm gonna lob a nade. What, I should "face you like a man" and do the circle-jerk with you to see whos the better dancer.

I think not.

I'm going to toss a nade into your perceived location (in which case this guy was CORRECT in thinking there was an enemy nearby), and see what I catch.

Sorry that you're pissed off that you're camping has been hampered.
