I know it's a meme but introversion != crippling shyness/social awkwardness, it just means that you "gain energy" when you're alone whereas extroverts "gain energy" from being with other people.
I don't know where on that spectrum I'm flying, but I've been adopted by an extrovert and then introduced to her friends. That meant a lot for me and I'm incredibly thankful.
Patently false. I'm introverted and made plenty of friends myself. You just wait in a corner of the party and see who comes and joins you without a word for half an hour.
