Person A:woah these 2 people look like amazing siblings.
Person B:Oh! I actually ship them and they are not siblings.
Person A:weirdo they look like siblings.
Person B: woah! This is like the akikasa effect that the great old kodster once spoke about!
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.
