new it's probably something to do with the way I was brought up. My mother was the same. I'm from a "respectable" family in a small village, and appearances meant everything.
My mother always had what she called an "inferiority complex" based on how she behaved. We were a close family , but there was little warmth. Duty, however, was important. As long as you were perceived to be doing your duty, that was fine. This way of being was passed on to me, and as an only girl child expectations were high. Achievement didn't matter so much as doing the "right thing". My mother died ten years ago but I'm still living by the mantra. This is why, I think, I was happy to be a sahm when dd was unexpectedly born as I perceived being a sahm equated to "doing the right thing". I don't think this has made me a better parent, by the way. But I feel that I have, in my own mind, "done my duty" to her. I'm satisfied with that, but it has come at a price.
I think you're right in that things are different for men. I notice that the parents who stress over their kids are invariably women. So if I take dd and her friends somewhere for a day out it is seen as just something I do as part of my role as a parent. It's not noteworthy. If, however, dp takes her on a similar day out it is seen as a massive achievement, to be planned, talked about at length and then crowed over.
Same thing with my useless cousin growing up. No matter what I did it was minimised and taken for granted. The slightest thing he did was greeted with cries of "well done". Clever boy!!
So what I think I'm saying albeit in a roundabout way is that expectations of women and men are or have been, different (at least for my generation). Women have had to fight to be recognised for achievements outside the home whereas men have just been men not needing further validation. I've always had to fight to be taken seriously, both as a young woman in the world if work, and perhaps I'm still fighting that fight, even if it's only with myself!
I'm intrigued as to why those of you who feel no need for an "identity" manage it.
Because I can't quite seem to...
