kb might have thought your first response beginning "it's not like" and including the phrase "of course" to be disrespectful. It's hard to calibrate respect when all we have are words on a screen, but a good way to begin a response is "Thanks for considering my question. I appreciate it. What I mean is . . . " Something like that is useful to invite more interactiveness.

Note: I'm just chiming in here because you asked. I appreciate that it might be difficult for a well-intentioned writer to see what others might see.
