According to Buddha

A friend endowed with these seven qualities is worth associating with. He gives what is beautiful, hard to give, does what is hard to do, endures painful, ill-spoken words. His secrets he tells you, your secrets he keeps. When misfortunes strike, he doesn’t abandon you; when you’re down & out, doesn’t look down on you. A person in whom these traits are found, is a friend to be cultivated by anyone wanting a friend.

when the sun shines, we’ll shine together
told you i’d be here forever
said i’ll always be a friend
took an oath i’ma stick it out ’til the end
now that it’s raining more than ever
know that we’ll still have each other
you can stand under my umbrella
you can stand under my umbrella
(ella ella eh eh eh)
