Replying to Guys I think I Creeped out MAc DeMarco

I was at Pitchfork fest today and my friends saw Mac DeMarco in a VIP only area, my cousin was playing and got me a VIP pass for three days so i went to see him. I was eating a slice of pizza that was about 1/6 of a whole round pizza. I climbed up the steps shook his hand and said "I know where you're sleeping tonight" because I thought he was sleeping at my cousins house. We proceed to talk for a few minutes about My cousins band and then the camo bucket hats he and Andy Boay bought outside. Then i ask him to meet my friends cuz they are big fans. A very shitty act begins and we stop talking, 5 minutes later he leaves.

tl;dr I told mac demarco i knew where he was sleeping but ended up being incorrect
