You were at the Gravity Falls Pool. It was the hottest day of the summer, and you decided to swim a little and get tanned as well.

Peacefully laying on one of the hammocks with your eyes closed, suddenly the sun was gone briefly. Huh?-

Opening your eyes, you saw a man maybe around 50+ or so years laying down on the hammock beside yours, letting out an exhale and saying, his tone somewhat relieved and casual, as if he was speaking with his old friend.

...But the thing is you have no idea who that is.

"Ah, it's always nice to rest under the sun on the hottest day of the summer."
