I dive with lots of different people through my dive club, and through working as a DM, and for the most part, I really enjoy it. However, I have yet to find that person who loves diving as much as I do, and also needs a dedicated buddy (like me) who wants to go diving all the time (like me!)
I wish I had someone who I could have as a regular buddy, not so that I could dive with them exclusively, but so I could dive with someone I knew and trusted regularly, who liked the same types of diving I do. It's kind of a bummer when I go to a dive-club dive, and end up diving with someone who wants to spearfish, while I would rather wander around slowly and just look at all the fish and other organisms in their natural habitats.
Also, dive-club dives are usually only once a month, and I want to find someone else who wants to dive every week (or even better, every day!)
There are lots of people I like to dive with. They just don't dive often enough for me!
