Et tu, Brute?

“And you, Brutus?”

Or “You too, Brutus?”. This Latin quote appears in William Shakespeare’s play “Julius Caesar” at the very moment of Caesar’s assassination. Upon recognizing his friend, Marcus Junius Brutus, as one of the assassins, Julius Caesar utters these last words. That scene is very tragic indeed, but nowadays, the phrase can be used jokingly to condemn a friend’s change of heart.
