The number of VNs you have also shouldn't affect the speed of a game, unless your storage space is almost full... or if you are running a bunch of them at the same time.
Funny that you felt that that was a good representation of introverts... I am severely introverted and I didn't quite agree: I like to spend almost all my time by myself, but I'm not shy or socially awkward at all... in fact, I get along with most people very well and feel confident in my interactions. Being social just drains my batteries, whereas being alone recharges them.
Understandable, and I'm sorry: that must be tough to deal with.
Most extroverts think that we're all socially awkward and shy... that's something that can be true for both introverts and extroverts. I know some really socially awkward extroverts.
Just because of that misconception, I kind of bristle when it becomes an introvert stereotype.
