Rudely decline the invitation
From Create Your Own Story
"Fuck off, pervert", you shout, "You and your freak wife can go to hell!". You walk past them and get back in line for the water slide, still covering your boobs. After a few minutes, you realize that maybe you overreacted. Yeah, it was an abrupt request, but they seemed nice. If only you could apologize. But, they're long gone by now. The line is extremely long and you decide one more time is enough. You get to the top and a child cuts in front of you.
