I teach little kids how to swim, I'm only 17. Oh, and you older guys with kids, be nice to the swim instructors, they're there getting kicked in the balls by your kids while trying to get them to let go of the wall (Don't say it doesn't happen, I've been nailed hard by some kids) and they're supposed to do it with a smile. Understand that they are trying to do their job as best as they can, most have a couple years experience as competitive swimmers (I've got 11, 11 years expereince in any job is impressive, mine just happens to involve wearing no shirt) and usually quite a bit as a swim insturctor too. Be nice, understand that your kid may cry, let them do their jobs and if your kid is hard to work with because they're scared, kind of unruly or something like that bring food. Swim instructors love food. We're suckers for stuff like that.
