@vonny,
I've a friend of the long time sort who once had two, count 'em, two, pulis. She and they lived in a small cottage near our uni. They didn't like me. I took it to be that I smoked back in those days and must have smelled of it, or else they didn't like any other interlopers either. Also, I don't remember that she ever worked up giving them the dreadlock look. She had enough going on without that..
