Today I've been thinking about a french phrase called 'esprit d'escalier', which translates to mean 'the wit of the staircase'. This refers to the moment when you remember that perfect comeback, the witty response, the snide remark, to that argument you had half an hour ago.

"Esprit d'escalier. The answer you cannot make, the pattern you cannot complete till afterwards it suddenly comes to you when it is too late."
