The point of pointing our the CESA was not so he would do it but to show that he really doesn't know much about diving yet. I don't think he's ready, bottom line is my opinion.
I would NOT want him to be my buddy if we had to do a dive today.
Further more I do believe he is serious about scrubbing the pool.
And I do understand that although the gear he bought me was a gift, it is still his gear since he paid for it.
But that's not the case.
If everyone truly thinks it's not a big deal then ok I'll agree with that.
So lets say I do go in with him. I do not want to dive alone, under no circumstances, 8ft pool or 80ft open water. So if I brief him and we go in together how should I do it.
Scrub the pool with my back turned while he frolics around, or watch him like a hawk while he does it.
Keep in mind he has only had 2 pool sessions, and what I believe is very little knowledge of his gear.
