I sometimes swim at my small local pool, which is usually divided in two, half for kids and families, half for swimming back and forth. And I regularly meet the following:
- the very large elderly gentleman who with great precision and impressive slowness swims back and forth in the precise middle of the swimmers lanes, forcing everyone else to swim in circles around him
- the cute so-much-in-love couple in their 40s, who stop to flirt and splash around and lie down, completely blocking all the lanes and oblivious to the swimmers trying to pass without grabbing a foot
- the athletic serious dude wearing goggles and a HRM who does all kinds of drills and swims very energetically - but not very fast
- the skinny pregnant woman who dogpaddles the entire length of the pool, back and forth, without stopping

But the best was the little girl who, when I stopped in front of her wearing goggles, cap and noseclip, stared and asked seriously:

"Are you a woman or a man?"
