What’s up with chicks and science?

Early evening at the Avant-Garde Bar. My mom is sitting in her usual spot, working on her laptop, while my dad is tending to the customers. The opening band is getting set up for their performance and the rest of musicians are curiously wandering around the bar, looking at posters. One of them approaches my mom for a chat:

“What’s that on your screen?” – he points to the pdf of a mathematics book that my mom is using as a reference for a math lesson she is preparing.
– It’s a math book.
– Oh, what’s your profession?
– I’m a mathematician.
– A musician?
– No, a mathematician.
– What? You are a magician?
– I’m a mathematician.
Awkward silence. Looks confused for a few seconds and decides to give up on a conversation. Rejoins the rest of the band.

Ring of the curtain.
