Is it normal that my wife is more freaked out than even me about having to dress as balerinas for a costume?

Greetings sir. I see your point, it is rather unusual for her to be freaked out at the prospect of dressing as a ballerina, considering that she is a woman. I'm afraid you have misread her. I highly doubt her fear and disgust is coming from imagining herself in a dress. I believe that she is disgusted at the prospect of seeing you in the dress, because as you two both know, it is the same dress you like to wear when you jerk off to transvestite and stick foreign objects in your orifice. Perhaps there is something about your behavior that triggers a "I married a " response in her. She is most likely in fear of what others will say about you, especially when you sport a giant b0ner walking around at the party in a tutu. I hope I cleared things up. Have a happy and healthy day, you heathen freak.
