ARGHH MY SISTER!

Is basically making ME help her plan my bridal shower! She's telling me all the places she's calling and for what date and even asking me to call places for prices. I'm really mad about this! I want to be surprised! I keep telling her I want it to be a surprise and she just says 'well you would just figure it out anyway.' UGH.
I can't wait until she gets engaged one day so I can ruin it for her!
Thanks for letting me vent.
