Good point, Stan. I have vivid memories of the very young French divemaster on my first warm-water trip (in the Seychelles). He was the model of relaxation and economy of movement. I leaned a lot by observing and copying him.
Yesterday I heard from a new diver who did her open water checkouts last month in our cold dark lake. Her buddy panicked on an air-sharing ascent drill and she came up pretty shaken by the experience. I was there as an assistant and I drifted over to her and just stayed quietly with her, allowing her to relax and re-gain her composure. I think I asked one question and offered one suggestion. I didn't think too much of it at the time.
Yesterday I heard from her that she came up thinking she was done with scuba. She wouldn't have gone back under, she says, if I hadn't just floated calmly on the surface with her and allowed her the space and time to relax and regain her own confidence.
So maybe I'm now able to model relaxation for others . . .
