Thanks Perna,
I think you re probably right about "that" look.

it really freaks me out though. will have to work harder at rationalising it.
i was thinking of sending her a christmas card but feel maybe she might not want to hear from me outside sessions or might think i was being weird / dependent / too needy / expecting something/ etcetcetc. think i ll just send her one anyway and judge the reaction later to see if it oversteps the bounds or whatever.
thanks again for your reply.
take care
