For good reason, Friendship is a popular theme! People sing about it, write poems about it, and even dedicate TV shows that play up the "Friends" theme!
And friends really can be a saving grace in our lives! A tender mercy! Spending time with amazing friends that I only get to see occasionally is great therapy! There isn't a pill or drink in the world that could give me the same motivation and sense of well being than I get from good friends!
"What greater gift dost thou bestow,
What greater goodness can we know
Than Christlike friends, whose gentle ways
Strengthen our faith, enrich our days."
-2nd verse of the hymn "Each Life That Touches Ours for Good"
