my instructor insisted that I remember SORTED:
Signal
Orient
Regulator
Time
Equalize
and Dive
(for a pre-dive check)
For the life of me, I could remember SORTED, but not what the heck it stood for! LOL I would just float there, suspended at the surface, looking blankly at her. LOL I would get the 'I'm dissapointed in you' look, and a big sigh, and then she'd repeat it for me...AGAIN.
As a thank you gift for all of her hard work and the time she devoted into turning me into a diver, I made her a small wall hanging in where I had stitched SORTED and it's description, along with lots of fish swimming around it.
It took me a couple of months to complete it, and I told her that with me working on it every single day, that I was sure that SORTED would be imprinted in my brain forever. LOL
She got a big kick out of my gift to her. She said that she laughs every time she looks at it, and remembers me. LOL
