(based on Genesis 7—a story of creation)
The thing about friendship is that it's often easier to recognize it's absence than it's presence. For many of his neighbors, Noah was just the kindly old kook who lived across the way. Sure he always had a encouraging smile, a helping hand, a listening ear, good humor, sage advice and food to share, but sadly, at their own loss, few labeled that "friendship," although all benefited from it.
Because we place so little significance on friendship itself, more on its absence, it's hard to think of the quiet grace of friendship or neighborliness as being a major theme of the Noah epic. In fact, neighborliness is such a quiet grace that we would likely not have the Noah story if it were not for the dramatic ironies that come in to stir the pot.
