Dude, just deal with it bro, avoid her. Stay at places around the house where she wouldn't be there, try to find excuses not to be in the house. And lets face it, I don't think she is living with you forever?
Don't hate her much :]
you'll never know..
the saying "the more you hate the more you love"
might come true with you guys >.<
nah :]] just saying.. ignore her.. thinking about her is a waste if you don't really like her. and also, minding her is consuming your time :]
I GUESS IF YOUR STILL A MINOR ALL YOU REALLY CAN DO IS BIDE YOUR TIME AND STEER CLEAR....OF YOUR SISTER'S FRIEND...IS IT? YOU NEVER REALLY SPECIFIED WHO SHE IS IM JUST ASSUMING AS IT SOUNDS LOGICAL AND YOUR OBVIOUSLY UPSET. ONE, MAKE YOUR POINT CLEAR ON WHERE YOU STAND WITH HER AND TELL HER TO KICK ROCKS AS FAR AS WHAT SHE WANTS. OTHER THAN THAT...PUT UR BIG BOY SHOES ON AND DON'T GO POSTAL ON HER ASS...
