I think there are good things about introverts and extroverts, and most people can identify with bits of each. I think a lot of people see being introverted as the less desirable, meaning antisocial and boring when it's certainly not always the case. If anyone is interested in the topic, Quiet by Susan Cain is a super interesting book!being extroverted isn’t a negative thing it’s a blessing.
Though it could be that Fleur has more spare time so is able to socialise more. Like if I got home from a trip I would be like oh better do x, y, z and make sure I get some sleep ready to be back at the office all week!
