As an adult you don't really consider
your friends' parents a whole lot (do you even know their names?),
but as a kid, they can potentially have about as much impact, as much
influence as your own. Especially if it's like your BFF.
Countless sleepovers, after school times that run into dinner times,
tagging along on family trips, our friends' parents had to feed us,
care for us, love us (or pretend to), discipline us, very, very
often. Think about it, on sitcoms there is almost always the
omnipresent neighbor or friend who is part of the every day fabric of
the protagonist family.
