Heck, I figured the picture was saying "Here I am, teaching my children to swim." I'm assuming the lady is a single mother and says so in her profile. In which case, this picture makes a great way of weeding out replies from guys who aren't ready to date a woman with kids. If the guy replies after seeing that, he's got strong potential.
In other words, I see nothing wrong with the picture. (Granted, I wouldn't respond to the woman depicted... but I'm one of those guys who isn't interested in dating someone with kids. And I know it.)
That photo says "Unlike all the women who have close-up shots of their face at weird angles in order to hide their chins and jowls, I am not a boat-hipped pig, so buy ME dinner, have enthusiastic but tedious with ME then marry ME at some halfwit catering hall and fill ME with your sperm so that WE might have babies."
"I look damn good, even when I'm paying attention to something else and not sucking it in. I am the kind of impractical girl who wears sunglasses in the pool. But most of all, I LIKE CHILDREN. I WILL DEVOTE ALL MY POWERS TO BEARING AND RAISING UP YOUR OFFSPRING."
Chilling, at least for those of us who is playaz in this particular game.
