House Plants

After a week of playing in the mountains, I had done my laundry and was putting it away when something caught my eye--Look carefully at the picture:
Apparently, when I was gone, this plant had grown through the window and in to my bedroom! (Top left corner of the window) Clearly I'm more of a green thumb when I'm out of the state. Too bad it wasn't a magical bean stalk! How does that even happen?!
