Because my mutant power is gender transformation. Whenever my relatives come to visit, I can't help using my power. When a man is clutching his stomach and rolling around on the floor, he gets really irritable. At times like that, he knows exactly how women feel. The thing he hates hearing most is: "Drink more hot water." The man in the wheelchair gently offered me a glass of water. Me: ... "Fuck! Get lost!"
