Unk

I have hired a half-orc I am going to call "Unk". I met him in the market and asked if he was looking for work and he only told me "unk". When I walked away he followed me and he has been following me ever since. I wonder if that counts as a contract? He is a remarkably unresponsive fellow, only ever saying "unk" and that rarely. I told him he could put his goods in the cart and in half an hour he was back with a barrel of the cheapest wine imaginable. That and his armour and weapon (a massive double headed axe) seem to be his only possessions.
