Your hope may just come true. Crows are extremely intelligent and they live quite a long time. When I was a kid I went on a vacation with my family to a cabin by a lake. A man living in the neighborhood had a pet crow. The crow would get cosy around our dining table that was outside trying to grab some food, so my mother chased it away once. After that for the next 2 weeks we stayed there the crow would fly over every day and take a shit on my mother's laundry. There were 5 people in the family, but the crow would somehow always pick my mother's clothes. This is a true story.
