The Minions Happiness and Friendship

The Minions are happy for most of the time but what is the secret to their success? Are The Minions happiness authentic or is it superficial? How does friendship play a role in The Minions' happiness and do The Minions build the same type of friendship that Gru and Scarlett Overkill do? Perhaps Aristotle can give us a little insight in how the Minions practice happiness and friendship.
