I was boiling the (electric) kettle to make a pot of tea, when Alex, who was playing on his computer, asked me to turn on the lights for him, because it was getting dark. And then I realised (for the nth time) how nice it is to have electricity.
Electricity make me warm and lets me have hot water. It makes working in this computer possible, gives me light. I like candles, but I would be even more blind if I had to knit or read to the light of a candle. Electricity cooks my foot.
It is something that we take for granted. But sometimes I remember how much is possible thanks to electricity, and I marvel at the little travelling electrons, and thank the for the comfort they give me.
I must admit that I was struggling to find something for E, but then electricity struck me (pun intended) so much that I actually mentioned to Alex that it was great to have it, and I thought it deserved some thanks.
