Happened to my Mom’s family when she was a young girl. My Mother has ALWAYS been really paranoid about lightning; not using the phone, staying in the middle of the house, etc.
Now, I know these are basic precautions, but she was always way over the top (she won’t use her cell phone during a storm..or the cordless phone)...wouldn’t let us run any water, etc. Anyway, it all made sense a few years ago when she told us about the ball of lightning that had entered the kitchen of her girlhood home, stayed awhile bouncing around on the floor, and left after destroying the phone. Apparently it was quite the experience.
I feel a little funny about using the water during a thunderstorm too after a plumber told me that lightning unsoldered every single fitting in a house he was called to service.
