Each family can be relatively large, mine is made up of 7 people. The 7 for good luck I guess. Not too big and not too small.
And I want to say that I only consider 7 people in my family as “My family”
(I don't know if I'm making myself clear).
I have a large family across the country, but I don't know most of them and I'm not very close to the ones I do know. Among that crowd I highlight 7 people who are the closest to me.
