I don't know what the NDA is, but for me, it's common sense, so theres no "I make more than you! Ha!" or "Why does he make more than me if he sucks at his job?" going on.
The first day was fun! I got to yell at like fifty kids for running.. around 5 cared what I had to say! I saw my 8th grade math teacher at the kiddie pool (with his kiddie) and basically rotated between two kiddie pools, a waterslide, and the bottom of the waterslide (all kiddie equipment). The nice thing about kiddie stuff is there is nearly zero posibility of drowning, or even getting hurt, so the kiddie pools was 'sit at the edge and make sure nothing bad happens', the bottom of the slide was 'stare at your feet and think' (splash waves would come hit your feet, because of the way the bottom is built, and you could tell when someone got down), and the top was pretty much 'you can go.. wait 30 seconds.. you can go..'. It's definately not the best job in the world, sure (I'd personally love a desk job programming right around now, actually), but it's definately not the worst (frycook, nay, busperson) and the indoor areas aren't that humid after you get your first good drenching and you're semi-wet. I think there were at least five points in the day where I totally forgot I was actually working.
EDIT -
Oh, and now that I've (temporarily, perhaps) quit WoW, I plan on going workaholic-mode on this job for a while. Shopping list!:
MacBook
iPod
Wireless router (for MacBook)
Phone line (Sounds stupid, but parents and I, plus friend, agreed it'd be a good move, plus the house is already wired for it).
More to come.
