There! I think she's got the message now. I'm sure she doesn't even think about leaving me on my own for a too long time.
The other things I've done during her bedtime have freaked her out too pretty well. I have found some annoyingly noisy toys to play with just the same time as she's trying to go to sleep. She has had to get up from the bed many times to hide the toys from me! We'll see if I've had enough of revenging already, or maybe just a bit more still...
