We always thought the “old” people that came to swim laps at the pool were a total bummer. We would be having fun jumping around and splashing and stuff and then “Beeeeeeeeeeep! Everyone please exit the pool for adult swim time.” And then 3 old women and one dude would spring out from behind some chairs and swim laps for 20 minutes. Then “Beeeeeeeeeeep! General swim now resumes.” and 50 kids would simultaneously all cannonball back into the pool.
