You can think of a lot of heartbreak condition, but this time, all I can think of heartbreak is: when your grandpa who has lived for almost the entire of your life together no longer remember your name. He remembered you as one of his grandchildren, he knew exactly which of his son/daughter’s children you are, but he don’t remember your name. He don’t remember what are you doing currently, he don’t know what to say anymore, he is no longer able to be the same man I grew up with. He thought you were still living in your hometown, he thought you were still young.
But when he said, “you look skinny, haven’t you eat? You should eat much. You should eat enough”, the heartbreak has just gone away, changed into a very warm feeling in the heart. He still cared for you, that’s what’s more important. :’)
