(Q - ??: so doubt on the ground but also before leaving?)
MB : before leaving, the truth is that the Super Solution is not a trivial thing, not a little calculation that you do in the back of your mind, it's a real find, it's a real trick and when we say to ourselves "good god but of course, how did I manage not to see it before!" and what's going to happen, at that moment, the no one who will understand, a finger will be said but it is certain that it is that and afterward, indeed on the ground there is still a little doubt, a doubt which will be played out but it is a doubt which stay comfortable, thoughtful and we understand.
