She gifted her mother-in-law a Kindle (digital reading device), but her mother-in-law (being of the older generation) never used it.
Several times after the death of her mother-in-law, she noticed her own Kindle would be on in the middle of the night, although she always thought she was sure to turn it off after reading in bed before falling asleep.
One night, her husband had a dream about his mother. Waking from the dream, he got up to go use the bathroom.
When he came back to bed, his wife’s Kindle was turned on!
