"I love you. Go to hell." is an expression. It exhorts someone to reciprocate affectionately (while damning them to hell). It was thought by Anaxagoras to be rarely spoken. Plato pointed out that it may be said more often than Anaxagoras thought, as there's a thin line between love and hatred. This love-hatred property has been generalized as "A thing and its opposite are almost the same." Then came the bingle bells. Double stakes. Let's have a war - I'm buying. Ain't gonna run around on you, Vietnam.
