I think most ISTJ/INTJ/INTP/ISTP's are commonly asked these questions upon first meeting. I know I am. I'd like to hear how you guys have responded to them and what reactions your responses normally produce.
- Are you angry?
- What's wrong?
- Are you always this quiet?
- Smile! (Okay. Not a question but I'm curious as to what types keep suggesting this questionable deed! ).
Other types are welcome to add their own "first impression" questions and answers. It would be interesting to see what some of the extroverts hear all the time.
