Lilly had friends sleep over the last few nights and this just heightened my frustration but tonight was the night, Mom and Dad were out and I was pla...ning some devious activities! This time I wanted to sneak into her room, under the bed and then see what happened. It didn't take long to find out!I took my chance while Lilly was on the phone to sneak under her bed, it was just a matter of waiting now for her to come in and go to sleep. It seemed like an hour when she came in still talking on. She always enjoyed being with me, even told me how much she loves it.'Why? We both enjoy and like what we do.
