One of the first things that children learn is to label the people (especially adults) in their lives.
Mum and Dad.
Aunt and Uncle.
And even as our world broadens and we meet more people, some related to us and some not, these four terms of address remain our most frequently used ones.
But do we ever learn what these terms really mean?
Do we ever teach our children more than simply which biological relative is entitled to which label?
Do we ever teach our children about the kind of roles and responsibilities each label entails?
