Julie still has nights that she gets into mischief. Why just this last week she managed to knock the cable box off the top of my bedroom TV at around 3am. For the most part she will play with me in the evening and sleep pretty well during the night, but she is a nocturnal creature and she loves to venture through the dark house in search of......who knows what? She likes to do 'fly bys' in the wee wee hours of the morning. She makes her little Jetson flying sound and runs across the bed about 10 times...then she will settle in for awhile. I think it is just the nature of the beast to be active at night. As long as she isn't knocking stuff off the dresser or tables I can usually sleep through it.
