I'm Not an Asshole. I'm an Introvert

I can be loud at times, and I'm not shy, so a lot of people assume that I'm an extrovert. When I explain this to people, they ask me, "Well, if you're such an introvert, why are you talking to a group of strangers in an elevator? This is a social interaction that you initiated and could have easily avoided." I just shake my head at how misunderstood the word "introvert" is these days. For example, people think that if you're an introvert, you don't like parties.
