Robert Plant
Jelena is a biology teacher that's why she's pointing at the plant and the reason why she is smiling so broadly is that she has just proved to me that plants can sing. Yeah, I know they can, Robert Plant....

Bouncy sausage
Last weekend I took the four students in the photo on a surfing trip. January surfing in Norway might sound like a strange thing to do but I can assure you it's not strange at all, cold yes but strange...
