Last night I kept hearing  aloud chirping but it didn't sound like a cricket.   As I wandered through the house it would stop and then start again as I lay down to try and fall asleep.  This morning while cleaning the windows, when I opened the door to clean the glass I found the source of my midnight caller.  She must have been trying to get out.  The kids and I put her on a leaf and took her to the tree lined area in the front yard.  Evan thought she resembled an alien, he's kind of right.
