The yelling, or more like the unintelligible scrambles of your alien boss could be heard, the alien was likely yelling at your coworker, Nomamoto. When you looked over you saw Nomamoto standing there getting yelled at with her nose bleeding since she always got hit. When the alien went to hit her again, you got hit by the elbow of the alien In the nose. You spoke up and actually talked back to your boss which caught Nomamoto's attention.
Once the work day was over, you exit the factory by yourself to start walking home. Not getting far your coworker runs up to you and speaks up, with a piece of paper towel in her nose to stop the bleeding.
"Thanks for that back there! I'm Nomamoto."
She holds out a can of coffee, offering it to you, flashing you a slight smile showing her sharp teeth.
