My brother and I used to visit the home of a married couple , friends of our parents . We were always told to be on our best behaviour as she liked children but he didn’t . To us this was a challenge , even from quite young , and with them we learned to interpret and respond to faces , body language and voices . As children we had to make an effort , and learn that we were not the centre of the universe . Years later we were told that his dislike of children never included us , and we learned to like and respect him.
Thankfully our grandchildren are the centre of our universe , but maybe they don’t always need to know it .
