Of course I don't like parties. I'm a reclusive internet nerd who's posting on a Pokemon forum.
I've never understood their appeal, or what the point of them even is. How can you have fun with so much noise and music making your heart beat irregularly? I /could/ understand the appeal if it was just a get-together that was centered on having intelligent discussions with people. But parties aren't really about deep, mentally stimulating chats, are they? They're mostly about messing around whilst your brain is hindered by alcohol. I'd rather not make myself more uncontrollably stupid in front of others. I like more quiet, civilized gatherings. Something with some calm music playing in the background as you have a deep conversation with another person. And all that matters is the two of you talking. More personal, not just jumping from person to person like a maniac. I don't... really have the ability to have fun like that. It's weird, but I just don't feel it like other people do. Probably due to the fact that I'm constantly being assaulted by my nerves in situations with too many strangers. I don't think that helps.
Dancing though? I can understand having fun doing a physical activity. A dance party makes sense to me, even though I don't have much endurance. I like to dance.
