A sushi chef would be poor in teaching me about cooking fish, yes, but I believe I know cooking more than fish, and a sushi chef would be very good to teach me about fish.
You see? I can't communicate how amusing it is for me to stay "you see? " to you but I will try; you are Drusas, who one commented about my chosen nickname, as it was similar to yours.
The reason this amused me, or is ironic, is that my name is "Jussi", which sounds sort of like "you see". And the thing I like to do is mansplain. So... you see?
