Confidence, self image, some interests, one x chromosome. :)
For me, it was my eyebrows and my small ****, the women on my mums side all have big boobies, on my dads side, not so much!
Believe it or not, my breast size.
My mother's side of the family have always had tiny boobs,
but my Dad's side? WHOMPERS, MAN.
So I assume I got my breasts from his side.
One thing I do know, is that my hideously stubborn attitude and my anxiety comes from him too.
