Listen to your heart
Some people can have gut feelings about the worst things possible. Predicting the death of a family member, especially an older one, isn’t uncommon, but hopping aboard a flight to visit an elderly relative to say your final goodbyes is. And that’s exactly what this person did.
His grandma was suffering from cancer, but it was far too late for anybody to do anything. They decided against chemo to let grandma live her final days as comfortably as possible. The OP had a feeling that grandma wasn’t long for this world, so he flew to visit her on a Wednesday. Two days later and much earlier than the doctors predicted, she passed away.
