Last night, we were out until after dark. When we got home, we turned on all the lights, and were quietly working at our computers. A mouse chose that moment to scurry out from under the baseboard heater. I screamed and ran from the room. (We caught the mouse overnight, and released it in a meadow. I'm hoping he's a loner.)
So, I have no explanation for why it did not freak me out this morning when I saw that a mountain lion had walked past exactly the spot where I was sitting on the ground checking a trail camera. A mouse scares me but a mountain lion doesn't?
