When you go to the pre-season meeting and meet all of your fellow employees that are still in high school:

When you look at the schedule and see that you're scheduled to work both Friday AND Saturday night till close:

When you just sat down on break and a kid comes up and asks for a lifeguard in the other pool:

When a little kid drinks the pool water which is, like, 50% little kid pee:

When you hear a herd of kids running towards the pool gate:

When an attractive person comes in and you realize you're wearing you're super unflattering lifeguard swimsuit:

When it's finally lunch/dinner time and you run upstairs to get food...

....but then you see that it's just meat and cheese sandwiches:

When a patron makes a really lame joke but you have to laugh because that's essentially what you're paid to do:

When one of the kids calls you by your actual name instead of "Lifeguard":

When you walk in the bathroom and a little kid has pooped/peed everywhere EXCEPT the toilet:

When a super old person comes in to swim laps and you're afraid they won't finish their next lap:

When a family comes in to swim at 8:45 and you close at 9:

When you spend the entire summer complaining about how boring your job is....

But then next spring, when your boss calls to ask if you're coming back, you say yes anyways, because why not?

Maybe you'll get a big kid job next summer.
