How did you find your duo?

Pretty much just the title, I'm curious if people duo more with irl friends or if met online where you met!

I've gotten back into playing recently and want to try to hit my previous peak again but am struggling with solo queueing. My old duo is still my friend but doesn't really play val anymore. Sometimes I'll meet someone nice in game and we'll play more after but usually never play with each other again after a couple days.

Would love to hear fun stories if anyone has any about how they met their duo :)
