"The water is your friend..."

 "The water is your friend...you don't have to fight with water, just share the same spirit as the water, and it will help you move."
Alexandr Popov
It felt good to get back into the swimming pool today and I have signed up for another ten swimming lessons at Stirling university Sports centre. There are only five of us so we get individual tuition.
 
I have mentioned before the changing rooms are mixed with individual cubicles so hearing men in the next cubicle did not faze me. They seemed to be indulging in some kind of horseplay.
Suddenly it went quiet.
 
I thought no more of it until  one man said:
“ Now go and wash your hands.”
 
What were they up to? Answers on a postcard please.
