Pro in science. He is a hopeless romantic that dreads being alone. He calls the woman that he loves beautiful not hot. He makes sure the lucky girl he has in his life is ok at all times. He tries to be a good guy to everyone and is always trying to clear his past.
When some resigns or retires from a job, they are on "eternity leave". This can also refer to someone who has passed away, especially someone who worked somewhere for a long time, retired/resigned, then passed away later.
Oh I'm sorry, you didn't know that Kelly is on eternity leave? She resigned and moved to Hawaii!
With regrets I would like to inform you that my boss is officially on eternity leave. I will never see or hear them again. Ever.
