You consider your options

You crumple the note and toss it in the lake. Sabrina is going to pay, she went too far this time! There is no way you can walk around the camp in your birthday suit! Your authority would crumble! The campers are hardly taking you seriously as is.

You weigh your options. The lake has your camp, a college, and a town around it, each one with its little beach. To get to either of those places, you have to cross the small patch of woodland that separates them. Your clothes are probably somewhere in the town or the college. Knowing Sabrina, she would not have left them nearby. Maybe you can find them without getting spotted somehow? The college is to the northwest, while the town is to the northeast.

Or, you can try to go back into your cabin and just get dressed again. You are bound to cross paths with many campers if you do this, however. The thought of your walk of shame makes you shiver, but is the alternative better?

There is one last option. Go back into the lake and hide until nightfall before streaking back out. At night, you will be able to move without worrying too much about flashing bystanders. But can you wait for a whole day in the water? It seems almost as hard as streaking around. What will you do?
