There's a kind of people who are eccentric persnality or keeps their attitude regardless of how much opposite is to the attitude of the majority. That kind of people the majority use to call Black Ewes or White Crows.
This morning I met a white crow. Real white crow, not metaphorically.
At this time of year crows has babies in their nests, so they attack all approaching predators. Cats know it well and don't feel pleasant.
