Ostensibly, this thread only really applies to those who travel to tutor, although I suppose indirectly it also poses the question to the stayers at home as to how comfortable you make your students. So let me cut straight to the chase: a couple of years ago I had a Y12 lad, who worked at a small desk on the far end of the sofa in the living room. He just had one chair for himself. Now guess where the mum sat me: On the edge of the sofa. Not just the first time - every time (and there were several - at least it wasn't one of those instant-dropout miscreant cases). In your craziest dreams, would any of you even think of parking a student, or any guest, on a sofa's edge and expect them to sit there for an hour while giving quality tuition or other serious work?
