I sit on couch always in the right corner while my T sits on her chair few metres away facing me (not directly). There is little coffee table between us. Even if we both reached and streched we would not touch each other. I don´t know if that means she is too far or not.
I don´t take my shoes off so I always just sit with my feet down but I wish to take them up or sit on the floor but I don´t have enough courage to ask if I could.
