I've never seen a mouse blush. But speaking of meeces (points if you catch the reference)....
Last night we had a visitor in the control room. As I was looking for something in one of the cabinets, I saw a mouse scurry from behind the cabinet to a location under my workmate's desk. Did I tell her? Are you kidding? A couple of years ago someone found a small, harmless, non-venomous snake outside the control room. After she found out about it she was seeing snakes everywhere for the next two weeks. Nah, sometimes ignorance is bliss.
