I have gone really out of my way to look up my T on Facebook. Her profile is very private but her husband's is not. He posts photos pretty often and I can sometimes see what my T gets up to on weekends. I can also see comments my T makes and she has a good sense of humour. I've found out all sorts of things about my T like where she lives and that she has two young daughters and that she is good friends with the other T's that share the office space where she works. I like seeing that she's happy and seems to have a good and balanced life; it makes me feel more confident that she can help me to achieve this one day too.
I don't think I will ever tell her about all this though
