If Bobby loves Amy
And Amy loves Bobby
Then Bobby equals happy
And Amy equals happy
If Bobby loves Amy
And Amy not loves Bobby
Then Bobby not equals happy
And Amy not equals happy
If Bobby loves Amy
And Amy loves Mary
And Mary loves Bobby
Then Bobby and Amy and Mary not equals happy
If Bobby loves Amy
And Amy loves Bobby
And Mary loves Bobby
Then Bobby and Amy equals happy
And Mary not equals…
If Mary not loves Bobby
And Amy not loves Bobby
Then Bobby loves Bobby
If Amy loves Mary
And Mary loves Amy
And Mary and Amy loves Bobby
Then Mary and Amy equals happy
And Bobby equals happy happy happy
Happy happy happy Bobby!
