You nap in the dumpster. You have napped in a dumpster before (you are a bear, after all), so you assume it is okay. You are wrong. In the middle of your comfortable dumpster-nap, you wake to find four baby opossums chewing on your ears and screeching.
This is not safe.
This is incredibly unsafe.
You run from the dumpster. But you do not feel safe. You might not ever feel safe again.
You are a bear.
An unsafe bear.
