So my mother would have had me when she was 25/26.
I have a very early memory of the sound of her high heels. No idea why that stuck with me, but I know it's from when I was maximum 3 (we moved to a different house when I was 3). So she would have been 28/29 (which is so young to me now in my early 40's!). She must have been going on a night out or something and I've no idea why this particular occasion seems stuck in my head. Another recollection I have is her deciding she wanted to lose weight and taking an old battered bike from the shed and flying down the hill will me on the crossbar lol (rural - don't worry).
I'm always amused that my dd seems to think of me as 'Mammy' and not as a human so to speak lol.
