Harry Potter grew up with one disappointment in life after another. Life isn't exactly a thrill a minute when you live in a cupboard under the stairs. Hogwarts, a school of magic and mystery, would be amazing to anyone, but it was extra amazing to Harry Potter, a boy who had nothing. Not even parents.
As a result, Harry looks back at his time at Hogwarts with rose-colored glasses. In Harry Potter and the Cursed Child, Harry can't understand why his own son, Albus, isn't having the same magical, life-changing time that he had.
At forty, is Harry already too old to forget what life was like at ten years old? No wonder Albus is disappointed in his relationship with his dad. Harry can't remember what it was like to be his son's age, and can't relate to him at all. Someone should take off Harry's rose-colored glasses, smash them, and make sure he never utters an oculus reparo.
