Light Bulb Moment

Been out for a meal for the second night in a row and after eating out over the weekend it seems like an age since I've cooked anything.
Tonight l was out with former colleagues and it was lovely to see them but we had some somber moments when we talked about some sad news we have just heard about someone we all hold dear.
Realised when l've just got in that l've not done a blip so went into the garden where the lights had just come on.
I blippedone of these bulbs recently but not at night.
I've got quite a few in the garden and they are all white except for three that are multicoloured which l bought by mistake.
