What in the actual f*ck?

So we're having our anatomy scan on Wednesday and hopefully (fingers crossed) we will find out pink or blue. We have a huge dinner scheduled with our close friends and family to reveal the big surprise... Well my mom decides it's more important to go see Tony Stewart at Bass Pro Shops and "possibly" get an autograph and picture with a "bachelor who makes a ton of money", than to celebrate the sex of a child we've tried for over 3 years to get pregnant with. Sorry for the enormous run on sentence. Lol. But she still insists on being the first to know? Haha. Try the last. 
Sorry for the rant. Just feeling a little down in the dumps.
