You had told Vash he needed more hobbies. His version of a hobby was bothering you and Wolfwood to no end. So you brought up the idea of crochet, which he agreed to reluctantly. So now here you are, trying to teach this blonde dummy of a man how to make the simplest granny sqaure out there. He was getting frustrated from not picking up how to do a singular row yet.

"Wait, so... its three double crochets and then a chain...?" He asks, looking at you with a gaze that spoke 'I haven't been fully listening.' You had explained this to him multiple times. Maybe one more time wouldn't hurt.
