Going Through A Killer Period

(I was sitting at a table at a ‘get to know you’ with a few more girls than boys. One boy, telling a story. mentions that he cut himself and got blood on his shirt.)

Boy: “How do you get blood out of cloth, anyway? Does anyone actually know?”

Me: *offhanded* “Wash it in cold water with soap. If it dries, let it soak for a while.”

Boy: “Wait, how do you know how to get blood out of clothes?”

Me: “EVERY girl knows how to get blood out of clothes.”

Boy: *jokingly* “Why, because every girl is secretly a mass murderer?”

Me: “…”

Me: “Once a month…”

Boy: *horrified* “Oh. OH. NO! NEVERMIND!”

(He quickly found another table to sit at, while I stared in wonder at the others at the table.)

Me: “How is a period MORE terrifying than us being mass murderers?!”
