I love those humorous ideas! When I taught classes on Social Anxiety, many people hated that question. But when I was teaching assertiveness classes, there were variations of that question that people hated as well. Comments like, "you have an accent" or You're sure tall, short", "what happened to your hair?"
When people are nervous-- and many people are when they first meet, there is a tendency to make a comment on the first thing you notice. Rarely is it an act of meanness. But it still feels mean when you don't know what to say. Wherever you are vulnerable, be prepared, have something memorized to say. "Why are you so quiet"?
Oh, I'm just enjoying listening to the music, or I'm enjoying watching people." and smile.
Now- deflect.
When someone asks you a question, the spotlight stays on you when you respond. You must practice throwing the spotlight back to the other, or you're still trapped. Just throw back one of those starter questions we begin conversations with.
"So-how do you happen to be here?" " Do you work around here?"
Volunteer something about yourself, where you wouldn't mind if the conversation tilted in that direction.'Yah, I volunteer at the ___ with Mary."
Or tilt the quietness question, "I guess I love listening to music more than talking"
"I'm a bird-watcher so being quiet really helps."
The point is --where you deposit your answer is where the conversation is directed.
If you say, "well, I guess I've always been quiet"... you still leave the subject on being quiet, and if you stop there, they follow the bait, and will try to talk about being quiet.
Those boring starter questions are just to start breaking the ice- every culture has some version of them. So practice them so you can tilt the conversation where you wouldn't mind if it landed up talking about food, or music, or gardening, or your work.
It gives you a little oasis in the middle of the what is the hard part for many people- the beginning!
I stumbled along with everyone else when I first began, so don't give up. Practice the words out loud when you're home alone, so it gets imprinted on the brain.
