Sister tries to use bride's wedding for her own gender reveal, gets offended when refused: 'She said I was being selfish'

Did Millennials invent the gender reveal? We at least popularized it. But either way it's by far our worst contribution to culture.

The idea of it at least started out fairly tame but then social media got a hold of it and threw kerosene on the fire. Now you see the most outrageous and performative "gender reveals" complete with fireworks, airplanes, and a never-ending list of destructive additions at an ever-increasingly disruptive amount of locations and events.

What is it about "gender reveals" that brings out the most feral attitude in us? Is it simply like some sort of Lion King type of deal with the monkey holding Simba out over the pride declaring that reproduction has occurred? 

Congratulations. Now please keep it to yourself.

Lo and behold, this bride-to-be's pregnant sister decided that her wedding was the perfect platform for hard-launching the biological gender of her child. What a convenient idea! Everyone is already gathered together anyways so might as well just go ahead and declare it while you already have a captive audience. Just ignore the fact that the gathering and event weren't about you in the first place and you're pretty much good to go.
