That sums it up pretty nicely. I was hugely embarrassed to knock my own mask off, hey - who said that an OOG diver would have to be having a really bad day to lose their mask as well.
I have never understood why divers want to bait other divers because of their style of diving. Why would it matter to me what soemone elses approach to diving was unless I had to get in the water with them, so what is the point.
Yes, i made some changes, not so I can dive DIR style, but because I can see the simple reason for doing things in a different way.
Would I do a fundies course? At some point, possibly. Because of yesterday? maybe, but mostly because I think the only way to make a sensible decision about whether something is for me is to know the facts and base decisions on those, not on incorrect information.
