We human beings are very clever.
We always find an excuse to justify what we love to do.
Bobby loved non-vegetarian food.
He loved birds also and started working for The Ethical Treatment of Animals (PETA) organization, but now he found it difficult to eat fresh meat, as he could not stand killing animal by himself or for his sake.
Therefore, instead of becoming a vegetarian, he started taking frozen meat, though outwardly feeling guilty, on the pretext that he was not involved in the killing process and once when it is killed, why waste it.
