"Her own mother lived the latter years of her life in the horrible suspicion that electricity was dripping invisibly all over the house" (James Thurber).
My grandmother was afraid of telephones. Pointing out that millions of people used them everyday was no help. It was precisely this of which she was afraid. If she picked up the handset how could she know whom amongst these millions would be talking to her. Scary.
She also could not abide those newfangled teabag thingies. She complained they were too fiddly. Obviously the fact that they were weighed out in teaspoon-sized amounts in advance was convenient but snipping each one open with a pair of scissors in order to fill the teapot was just too much trouble.
I loved her dearly and named my eldesr daughter after her.
