Initially, the flakiness of my potential buddies. I wanted to dive and planned dives with people from my LDS’ “dive society” and their Facebook group. Sometimes it went well. Sometimes they didn’t show up, leaving me waiting at the beach with all my dive gear. Sometimes they showed up but forgot to fill their tank / bring their fins / how a regulator works, etc. Sometimes they seemed like squared away divers but then immediately swam off at five knots into the murk then berated me for being a bad buddy when we reconvened at the surface. At some point I felt that this wasn’t adding to my enjoyment or to my safety. Now I have a few very good buddy friends who I enjoy diving with enormously, but their presence isn’t required for me to get my periodic “fix” at the local dive site. This flexibility, and not having to hunt for random instabuddies, makes me a lot calmer and happier.
