Family member ruined gender reveal

My sister ruined my gender reveal, i am SO upset. I had my friend send a screenshot of my sneak peek results to my sister so that she cqn plan a gender reveal thing this weekend. Sure enough my sister sends me a text with a reaction foreshadowing the gender of the baby. (She wanted a boy, so the excited message i got from her gave it away completely.

I'm trying to be happy but i literally feel like she sucked all the magic out of this.

& it's even worse because i thought she was joking, so that I'd get all worked up and then this Sunday when we did the reveal I'd be even MORE surprised to see pink smoke. Because even tho she ruined it i thought maybe she's bullshitting me to make this more fun this weekend. But no, she was dead serious . Totally ruined it 😕

Am i being ridiculous?!?
