Cabbage Butterfly

I was sitting at the kitchen table editing a document and drinking hot tea, when I heard a beating of wings against the window.  It was in the inside, not the outside.  A cabbage butterfly.  I do not know how it got inside or where it found a place to grow and open in the house, but here it is in the middle of winter.  It soon gave up beating its wings against the window and found the orchids that were blooming and rested there.  What a lovely surprise.
