Besserwisser (know - better) is one of those words the English language has adopted. If there was ever a need to have a word for people who think they know everything better, even than the experts and are not shy of loudly telling everyone, it is now. Iceland just shut down again. I do not have the energy to be a Besserwisser about it anymore, so I just go and edit my volcano pictures.
Icelandic Horses are the embodiment of stoicism. In winter you see them standing in snow storms, perfectly still, ass towards the wind. covered in snow.
BTW snow at the end of march should be illegal....
