So that Toby came round with his girlfriend earlier to let her meet me. That went well, I was polite and not even a smidge inappropriate due to the circumstances. He came back later after her mum had picked her up and had food that I hade made (or opened the tin and microwaved). He then said that he was reasonably impressed with me being appropriate, apparently he had warned her on the way here earlier that I was likely to be mad. Shucks
