I've hesitated about posting here because my "best part" is a bit of a negative one. My childhood was really horrible, and both my brother and I were so scared of passing any of that on to another generation that we decided that our 'line' would stop with us.
DH and I met when we were still at school so he understood completely - he wasn't bothered about having children anyway, either then or in the 45 years since!
I don't think I could cope with the noise anyway, I like peace and quiet.
The other really good bit for me though is to do with cooking. When our DNs were young, my SIL would spend ages preparing healthy meals (with "hidden veggies") only for them to be rejected, either with a soundtrack of OTT retching or just a simple "mummy, not like" depending on the age of the child. Now, I love cooking, but some nights - such as tonight - I just cannot be arsed, so what am I currently eating? A chocolate orange, washed down with a lovely glass of Malbec. Cheers! 🍷
Edited to add, that makes me sound like a bit of a lush! I'm really not, I seldom drink alcohol but when I do, I don't feel guilty about buying a good bottle or two.
