@ElleGray when I am out gathering mussels at a jetty, because I am old and need to supplement my food budget, and the tourists in vacation homes come up and want to talk to me, I sometimes just say "I'm not friendly". As put off as they are by that, what I really want to say is, "I am not a god damn YouTube video. You don't have a licence, know when they are poisonous, or know how to cook them. So no, you shouldn't do this and I am not going to teach you for free!"
