There are all sorts of different families, Katie. Some families have one mommy, some families have one daddy, or two families. And some children live with their uncle or aunt. Some live with their grandparents, and some children live with foster parents. And some live in separate homes, in separate neighborhoods, in different areas of the country - and they may not see each other for days, or weeks, months... even years at a time. But if there's love, dear... those are the ties that bind, and you'll have a family in your heart, forever.
