Unless air sharing has been practiced and rehearsed many times, I think most buddies of the 'once or twice a year recreational divers' club are going to be more of a liability than help so I'd rather practice more, pay careful attention to my equipment and go diving alone than to take my chances with a stranger because we've all met divers who equate the number of dives they've made or the years they've been certified with competence and level headedness underwater.
And I don't mind admitting it because I'm sure the majority of people who're in danger of drowning do the same. I've almost drowned when I was young and the stranger I grabbed hold of (thinking it was my brother who happened to be a few metres away) probably felt that I had more arms than an octopus as I tried to grab and use him as a ladder to climb out of the water!
At that moment, even if someone had shoved a mouthpiece into my mouth and told me to stay calm, I'd have spat it out, choked him, pushed him under and stepped on his shoulders hoping to get to the surface.
