Extroverted what, though? Introverted what?

You can't just say "Oh boy am I an introvert." and just leave it at that.

Some people are extroverted picking their nose. Let me explain what I mean. That means they do it in front of others and don't give a fuck, or they might apologise when they get called out, and just do it all over again next minute. That's me. Other people are introverted picking their nose. They go away in private and they go ahead and pick their nose now that nobody is around. They're not necessarily in denial about it, and sometimes you can get them on the topic and compare notes. That's my wife.
