"You're so quiet! You never talk!"

When I was a kid, my peers would often say to me "You're so quiet!" "You never talk!" I had no idea what to say in response.

As an adult I'm better at thinking of clever responses than I was as a kid, but to this day I still have no idea what they wanted or expected me to say in response to that. Now I'd probably answer "You're so quiet!" with "Aren't you glad?" and "You never talk!" with "What do you want me to talk about?" (wide eyes, raised eyebrows, open hands, body language communicating that I'm ready and willing to talk about whatever it is but I have no idea what it is). But I still have no idea how they expected me to answer or what they were getting at.

Googling around this idea, I found stories of other people being asked outright "How come you never talk?" or "Are you always this quiet?" I think today I'd answer these questions with "It's either that or babble mindlessly. I suck at coming up with the appropriate quality and quantity of conversation." I've found in general that when I openly, matter-of-factly and unapologetically state my personality flaws, people act like they don't believe me or like they think I'm kidding, but it totally smooths over the potential tension from those personality flaws. For example, someone wanted to take my picture, so I said "Only if you let me fix my make-up first. I'm entirely too vain and shallow to let anyone take my picture with imperfect make-up." She acted like she thought I was kidding, but she still patiently waited while I fixed my make-up before she took the picture, which has NEVER happened before! Usually I get a candid picture taken against my will and/or a bunch of crap about being so vain and shallow as to not want my picture taken with a shiny forehead.
