Your enemy will not come with an unsavoury habit that will arouse suspicion; he comes with a charming garment, mostly white, with the inscription YOUR TRUSTED FRIEND boldly imprinted on the most conspicuous part. Then, you offer him a seat, then, a drink and a meal. Then, you share your secrets with him, and the ritual continues. And when he finally strikes, the enormity of the impact leaves you in utter wonder how it all happened. Listen, your foe was once your friend. What happened was that, while acting as the former, he came as a spy to survey your strengths and your weaknesses.
