her grass is greener.

is there usually a specific time of day that she would do this? im thinking. and this may sound REALLY retarded, but its an idea, when you know the next time she will be outside for a while, get a video camera, out it up at a clear view of where she usually "gets" you, and there you go, you have proof that you did nothing wrong, and she seems to be profiling you.
Does she do this every time she outside?
