I actually remember doing this as a kid. Mum's food always seemed better than mine, although I can't remember wanting to eat her dinner - just the "snacks" she would make, and always her drink! I am sure she shared more times than she wanted to.
I loved it when I could eat whatever I wanted to without having to share!
Lately I have found myself sneaking to the cupboard and very quietly getting something to eat so that I don't have to share it ha ha! Surely I'm not the only person who does this? As soon as there is a crinkle of paper, or even a slight noise in the cupboard, I hear an instant patter of footsteps making their way to the kitchen..."mummy more?"
Maybe I should apply this to my life..."Sharing is good because it makes everyone happy"
