How to Care for Introverts (Understanding Our Gifted, November, 1988)

• Respect their need for privacy.
• Never embarrass them in public.
• Let them observe first in new situations.
• Give them time to think. Don't demand instant answers.
• Don't interrupt them.
• Give them advanced notice of expected changes in their lives.
• Give them 15 minute warnings to finish whatever they are doing before calling them to dinner or moving to the next activity.
Reprimand them privately.
• Teach them new skills privately rather than in public.
• Enable them to find one best friend who has similar interests and abilities; encourage this relationship even if the friend moves.
• Do not push them to make lots of friends.
• Respect their introversion.
• Don't try to remake them into extroverts.

So true, some people need to learn about this.
