Oona wasn't entirely sure why the guy got on her nerves since she had just met him. 
he did have a point usually she would have just said it wasn't the guy's fault and gone to take a shower, but something about him just drove her up the wall.
 "do you know how hard it is to get stains out of white hair?!" 
Oona was a little sorry for yelling at him but wasn't about to apologize, as the guy had just yelled at her as well.
