Is that why you had to leave your dd home so you could leave the door open for the cats...
I picked the jem up about spacial awareness form somewhere. My dd does go out and cross the road along and she has been playing out for a good two years now (10years) but in the busy mornings I always tell her to go to the lolipop man as I am far more concerned about the road crossing at busy time than other things.
Told my dad about this thread and he told me the first time he was left alone was in 1944, he was 4 - there was a war on and he lived in London, and his mum went to the co op, the lady next door (upstairs flat) kept and eye through the window.
He cleaned the lino with the front door red polish!! He was helping mother
