I wonder the same thing. I was pretty attached to my T (thought I worked very hard not to let it get out of control) but my whole life, even as a little girl, I always got attached to older women, usually teachers. I saw them as mother figures.
My mom was always there, and she does love me, but she is not super emotional/touchy-feely/expressive. Neither am I, though. I don't know why I so longed for the motherly love of teachers I've had.
