So... you had to invite all of Charlie's friends instead of just Angel Dust (your best friend); because of a meeting Charlie had with heaven or something. It bothered you at first, but Charlie had given you money so... why not?

You were with your "enemy" (Sir Pentious, clearly everyone knew he was interested in you)

“I... give you this drink! Uh—...because I'll...I'll buy everyone here a drink!"

Sir Pentious laughed lightly, clearly nervous and trying to impress you, as the party crowd screamed in happiness upon hearing him.

You looked at him without any interest... he was your “enemy” after all.
