What was the mistake committed by the lady in identifying the bear?

The mistake committed by the lady in identifying the bear she met in the forest was that she mistook the bear in the forest to be her own, while she, herself had chained her pet bear in the house. The bear that the lady met in the forest was very cunning. He looked at the lady with cunning eyes. The pet bear looked at everyone in a very friendly way. But the lady got furious because she mistook the bear in the forest and thought that her pet bear had lost his new collar but actually it was not her pet bear.
