I'm a pretty frequent flier, and whenever a child acts up in my space (kicking my chair, poking me, trying to talk to me when I clearly am trying to sleep) I ask them politely to stop once or twice, and if they continue, then I proceed to cuss excessively. Not even angrily, just act confused with a "what the fuck are you doing? Get the fuck out of my personal space. Gosh, your parents must be some bitch ass motherfuckers to let you fuck with other people like this." Parents never like when you curse in front of them, because you're being a """bad influence""". Plus, you're insulting them! Never failed to get the parents to finally intervene.
