I started the smash bros nights specifically to make friends post college as most of my college friends moved away. One of the guys I met online only once through a TTRPG discord and now he brings the good beer.
Also, whimsy can be everywhere. Step outside and watch a flower dance in the wind. Bam, whimsy. Go visit a cemetery and make up funny stories about what led to inscriptions on the tombstones as you map it for findagrave.com , bam, whimsy. You need zero friends for whimsy, but whimsy has led to many friends in my experience.
