Fence sitting is hard on the hiney, I will tell you that! My heart wants to believe he is refusing to cooperate because he was brainwashed by his dad into believing there is no one out there for him, and that it would be wrong to look. However, my hinkey meter is going "ding, ding, ding!"
My family and I are avid wilderness campers. After even only two days in the woods, my family and I would start to look a little ragged......after a week in the woods, I didn't have any nails left, certainly none that were "trimmed." We often camped next to creeks, and we would rinse ourselves off as best we could-----no soap, because we didn't want to harm the environment! You can get really clean just rinsing in a creek, but no way can you neatly trim your nails on a tree trunk or something!
I'm not sure what "chancer" means. If it means a young Czech might want a better life in a new place, I can see him entering Germany in search of a better life......but wouldn't German officials recognize the accent?
