Joke

One day my friend and her little sister were in a restaurant eating. The little sister suddenly raised her head and with a puzzled face asked, “Sister, what does ML mean ?” My friend looked at her with shock, her little sister was only 11 years old, just 11 years old…! What does ML mean ? My friend struggled for a while and then decided to tell her the truth, and with embarrassment said: “It means ‘make love’.” Her little sister then pointed at the drink box and asked: “Then what does 250 ML mean?” My friend immediately suffered an internal injury...hehe
