I recently read The Great Gatsby for the first time, and while the book is filled with all sorts of cleverness, a concept I particularly enjoyed was how much more private large parties are than small ones. At first this sounds backwards. How could you receive more privacy while being surrounded by way more people?! But it actually makes a lot of sense, particularly at massive parties. Massive parties provide more opportunity to blend-in; to be whoever you want and to act however you want. If you weren't feeling particularly social and preferred just to wander around the party, you could literally not to talk to anyone the entire night and no one would even notice or care. Imagine trying that at a small party. Conversely, if you were feeling social, you could choose exactly who you wanted to talk to and for how long. You'd have the ease to remain in a conversation you were enjoying, and the same ease to slip away if the conversation got stale. You could laugh with that person, dance with that person, hold hands with that person and no one would care at all. You could certainly do that at a small party, but it might be a little awkward.
"I like large parties. They’re so intimate. At small parties there isn’t any privacy."
-F. Scott Fitzgerald
