You are in the living room, waiting for her to finish showering, you just had a discussion with her because she doesn't help you cleaning the house and keeps making it dirtier.

You hear her shout from the shower:

"HEY YOU! COME HERE AND BRING ME A NEW SHAMPOO AND CLEAN CLOTHES! RIGHT NOW!"

what are you going to do, shout to her too, or try to calm her by talking calmly?
