What made you ponder if people can tell that they’re going to die?

My grandfather took everyone out to eat the day before he died. He was real sentimental about it, which was unusual for him. He was pretty rough around the edges. He was loving, but not super soft about it. When he passed away the following day, I began to wonder if he knew he was going to pass. To be fair, he had heart problems. But still — I feel like something made him aware his time had come.
