My colleague on the table is an aquarium with a pair of fish, well, as there were two, then one died, he drank the second and immediately the first broke off with small and slightly lost weight. Prior to the second fish, the first chased from food afterwards dying, and now the second chases the first. Moreover, he chases in a peculiar way, putting all his efforts on the persecution, at this time he does not eat himself. And the first, pleasant, has time to catch the dough of food, while the little ones also eat, and no one chases them. When the second fish is roasted, there is almost nothing. I think she even lost weight. There will be no morality.
