Home improvements - a new morning alarm call device

For once, Celia has made a real home improvement for me. Normally I dislike any change whatsoever to my home territory. Thoughtless humans go in for quite unnecessary alterations sometimes involving the intrusion of hunky men with builders' bottoms, dust, grinding and hammering noises, and a radio set loudly to Radio 1. (My musical tastes are classical as you can see from my profile.) This particular home improvement involved only a short visit, a little bit of hammering, but no dust. The intruder hung up blinds in my bedroom, the one I generously allow Celia to share with me. Celia's aim seems to have been to cut out the morning light which conveniently wakes her up in late spring around the time that I think is suitable - somewhere near 6am most mornings. She hopes to drowse in bed for a further hour. Luckily, although the light is now much reduced, the intruder has thoughtfully installed a wake-up device which I easily mastered. It consists of three pieces of rope with a nice little plastic toggle on the end. When the blind is pulled down this hangs down to the windowsill where I can reach it. This morning I woke her without any difficulty at all at 6am by swinging the toggle and smashing it against the windowpane several times.
Neat, eh? More fun that scratching the bed and less trouble than sitting on her face.
