A little rant

So usually its other people who organize your babyshower. Whether it be from your side or your husbands side. The other day, my hubby's sister and I were talking about games for camp and she started talking about how she wanted to play an egg roulette game at my baby shower.

"Oh yes, I really wanted to play this egg roulette game at your baby shower but since you aren't gonna have one, we don't get to play"

Um what? I don't mind if I don't have one but for some reason it made me really sad. Am I overreacting?
