I want to say something to challenge this stereotype:
But if it's a lot of people who want the image of being party people and want to be loud and outrageous but haven't really got the confidence or experience, and look for/to and rely on more outgoing people to coax them along and pull them along, it can be quite exhausting for the extraverted person who has to fulfil that role. You know, the one where, when you're in the room everyone's laughing and talking to each other sorta 'through' you, but if you leave the room for a couple of minutes and come back, they're all inspecting their fingernails and looking awkward and stilted. And if the host is someone you like and you know that something big for them is at stake, and that they need to have this party remembered by the other guests as a good time, the pressure on the extravert is quite high. It's not fun, it's not energizing or entertaining - it's hard work and thankless, cos you know that when the wine's worn off, everyone will remember that thanks to the host they had a great party, but you'll be remembered as the 'obnoxious' one who 'dominated' all the conversations.
Similarly, if it's a kind of party where people sit around and talk in small cliques or one-on-ones in long conversations about things they know about, it'd probably be quite energizing for the introverts and boring for the extravert - and boredom is tiring for me - being bored for a couple of hours in a room can make me feel like I've just run a marathon by the end of it.
Discuss/disagree/qualify at will, mes amis
How do you feel about parties? Are there different kinds of parties that you respond to differently, and how much does the type of other guests affect you? Extraverts - are you automatically energized simply because there are people around of any kind, or do you agree with me? Introverts - do you always dread every party, or do you sometimes find yourself enjoying yourself against your expectations and if so, what contributed to that?
