Al que juega con fuego se le queman las pestañas. You can erase the proof; go back or forward, empirically play with the possibilities even in real time. You can expose your weakness in a hearty confession, edit it or get rid of it. Better, you can turn it into a stony ultimatum and break a spirit or two.

It is against nature. It is just unfair.
