If you have to preface it with, “You probably don’t know this, but,” please don’t bother asking me the question. As a matter of fact, please don’t talk to me at all. Ever.
If you really don’t think I’ll know, why in the world are you asking? And if you think there’s a snowball’s chance that I WILL know, why are you insulting me before you ask for my help?
It’s like saying, “You’re probably too fat to climb the stairs” or “You’re probably too short to reach this thing on the shelf.”
Just quit being a jerk…but you’re probably too stupid for that.
