I once asked my T if I could give her a marble of mine which she could give back to me as a transitory object.

Unfortunately she felt that might foster dependency and gently declined...

She's going on a 4 to 6 month maternity leave so I'm really wishing I had thought to ask her to return two books I've loaned her months ago. I think having those books and thinking about how she's read bits of them during her spare time at work would be comforting to me.
