I was a huge introvert as a child (chubby, unpopular only child FTW!) and teenager (ditto) and my parents were both professionals (doctor/doctor). I guess I never really minded that they were rarely home. I spent a lot of time with extended family ... and I played GS! Given what I've seen, I'd rather what my parents did than smothering the kid, who is then unable to make decisions without input from others.
