Calliope definitely has a sense of humor. A fairly evil sense of humor, at that.

RT was concerned by about 8 o'clock last night that he had not seen her all day. Round and round the house he went, inside and out, calling her name and looking for her.

At each stopping place she was just behind and above him, out of sight. On the stairs at the top. In the tree above the garden. On a bookshelf just over head level. On the top of the car as he bent to look underneath. Silently slinking from station to station, shadowing him, while he called and called.

Finally he stopped and started to turn, saying to me, "I can't find..." and found himself none-to-nose with said cat, who hissed, fluffed up and sprinted off into the far corners. RT nearly had a heart attack.

I swear I heard a sneering meow from the shadowy hallway as she fled.
