You've got a beer or a margarita or a virgin daquiri in one hand and you're in the water and it's sunny, everyone's laughing and chatting, the music is good. Suddenly someone tosses a beach ball into the pool near you so you laugh and bat it towards other people who hit it around a bit more. It's not important but it's random fun and it's such a nice day.
The pool party is CoHost and the beach ball is Ryan Reynolds being turned into carbon.
