I see you around a lot and you’re always so quiet.
How come?
I ain’t quiet - everybody else is too loud.
I talk when I have something to say. Others could learn from my example.
I have to really watch what I say, otherwise my hatred for you and others will come spewing out uncontrollably. 
This.
I’m mentally texting you instead. Cuts down on the small talk.
I’m figuring out how to get rid of the long bones.

Standard answer: Umm… mumble… I don’t know…
It helps me avoid people who point out normal personality characteristics and suggest they are flaws.
… (Make mime gestures).
Because only idiots babble incessantly.
If someone else already said it. I ain’t gonna repeat it just to type.
:dubious:
There is a reason why a person has two ears and only one mouth.
Mom told me if I can’t say anything nice, don’t say anything at all.
Shhh - I’m picturing you naked
I’m mentally plotting out all of the escape routes.
I’m hunting wabbits.
Because I’m still figuring out which buttons I can push…
I’m usually only quiet until you get to know me. I tend to be a little shy at first, but I’m really pretty gregarious. Also, I’ve discovered that people will think you’re much more intelligent than you actually are if you only speak up when you know what you’re talking about.
