I think it is selfish to expect a person to play an extroverted role for the sake of entertaining you.
I tend to be highly introverted, and highly selfless. I know plenty of very extroverted people that I consider to be selfish.
Introversion and extroversion refer to how a person recharges, how they process new information, etc.
Selfishness vs. altruism is focused on whose needs you value.
Two completely different elements in my mind.
Personally I wouldn't class conversation as entertaining someone. Its conversation.
That said, I know about the extro/intro recharging NOW. So where as I cant get my head around how being alone allows someone to recharge their emotional state, I understand that that's just the way it is.
Back when I wasn't aware, and I thought that intro just meant shy and extro meant noisy (totally wrong I know, you can get shy extroverts, shock, horror), I had a friend who I now know to be an intro, when he wasn't paying any attention to stuff around him and appeared in his head, I thought he was just not interested in what we were doing and had no enthusiasm what so ever. And when he went to a social gathering and needed a couple of days to recharge, I thought he was being anti-social. That said I know about this stuff now.
If only they had taught basic things like the difference between intro and extro at school instead of stuff like history.
