100%. I thought I was good at making friends becuase I always had a friend group I could do stuff with. Turns out I just had a hobby that forced me to show up at the same place 1-2 times a week with the same group of people. I continued that hobby in every new city I moved to and easily "made friends" there.

It's kind of silly but honestly a lot of friendships are just the people one sees most often.
