1) If a person is introverted, it does NOT mean they are shy or anti-social.
Introverts have more brain activity in their frontal lobes and when these areas are activated through solitary activity, introverts become energized through processes such as problem solving, introspection, and complex thinking.
Extroverts on the other hand tend to have more activity in the back of their brain, areas that deal with processing sensory information from the external world, so they tend to search for external stimuli in the form of interacting with other people and the outside world to energize them.
2) Introverts tend to dislike small talk.
If you really want to engage an introvert in conversation, skip the small talk. Introverts tend to love deep conversations on subjects that interest them. They love to debate, go past the superficial and poke around the depths in people’s minds to see what’s really going on in there. Most, if not all introverts tend to regard small talk as a waste of time, unless it’s with someone new they just met.
