I'm usually not one for violence, but tip them ALL overboard and let them find their way back on board by themselves!

Your parents suck, your sister's gonna grow up a bitch & I feel sorry for her

screw it push he over if you are going to be in trouble at least have the satisfaction of doing something bad

My brother is the favorite in the family. And it's perfectly fine for him to be annoying as ****, but as soon as I threaten to punch him in the face then they start getting onto me. And the thing is they don't think I'll do it, but the only reason I haven't yet is because I know it'd **** up what modicum of a relationship i have left with these stupid idiots. So yeah, i know how you feel. and i would have shoved that little ***** head under water for pushing me out, especially if the boat was moving.

OP was the boat moving? That's seriously dangerous and your sisters a bitch for pushing you over. Your parents are assholes for taking her side when your could have been seriously injured.

Holy shit, this is like a real life Drake and Josh situation. Lmao

Shove her overboard and keep shoving her overboard every time she gets back on. May as well be hated for something you DID do for once.

I would've said "screw this, I'm swimming to shore," and jumped back off.

I'm going to say something some might hate... But you need to slap that little bitch. Do something so that she knows it's not tolerated. Show that you don't fear getting grounded by your parents. Who knows, do something so outrageous that even your parents thinks it's far out. But show that bitch it's not OK. Don't lie down and take it!

I bet that will be my sister later...
