One of definitions for “family” goes: A group of people who gather on the occasion of change of their quantity”. Quite witty, I admit.
For me a family does not comprise only of blood relatives. A family is a group of people who are I care for (for whatever reason) and who care for me. Yes, my family includes my friends.
Every family is different – nothing new there. But I also think that despite the differences inside a family, all the members have something in common. And I do not mean only the quarrels over the past!
Look at these trees. To me, a perfect illustration of what a family is. Very different each one of them, but still together, still alike in many ways.
