Input: So me and my older sister are never serious with each other. So last night me and my twin sister were in the living playing on the xbox one cuase my mom makes us keep it in the living room so she can use the blu ray player on it. So were sitting there playing dark souls 3 and my older sister comes up flops on the couch next to us and takes a pillow and screams into it. Then my twin sister says " what's wrong" and my older sister just keeps her face in the pillow. Then I say "what is it your time of the month" and both of my sisters start yelling at me saying shit like "what the fuck you never ask a girl that you have 6 sisters you should know that already" and more stuff like that I said I'm just joking and there still mad at me. AITA?

joking and asking my sister "if it's her time of the month"
