The friendly Miss C was well prepared for my visit this afternoon - a small footstool ensured I could reach her ceiling light fitting (with only a little occasional wobbling...) and she had a decent selection of old school filament lightbulbs which I could use to replace the two that had blown. After a brief discussion we decided it would be sensible to replace all three, and so after some up and downing to remove and replace each bulb, Miss C flicked the switch and her living room was bathed in light once more.
