team diving skills

[freedivernd]

For sure, team diving skills is one area I know I could use some work on.
So, I'm curious, what makes solo diving safe then? or in some cases safer? Is it always necessary to have a buddy? Is that an individual thing? (no pun intended). Is it a depth/time thing, meaning no deco?
I really want to know because I know my buddy skills, especially before a dive could use some work, and that means the during dive skills could use some work too. But yet, I have no qualms of doing scuba on my own as long as the depths and times are within my comfort zone.
I know when I'm freediving, a lot of time I'm alone. But if I'm instructing, then the student is never alone, and things never get pushed. And of course, I preach the always have a buddy but I could rarely freedive if I didn't go alone.
People who know me know I enjoy people but sometimes, I really enjoy a dive alone... is that a bad thing?
Mind you, I don't have 100's of scuba dives under my belt.. hardly any really, but that doesn't say much for how I react underwater.
Just talking about buddy skills will improve them, just like every dive so far I've learned something that worked or didn't so improvements have been made. One thing I've come to the conclusion of is that here where the vis is 3' everyone should be holding hands. Or should you be working on solo skills? I'm asking seriously.
