He was alone as a child and sent to boarding school.
He stole the Whos presents and they weren't sad because christmas wasn't about presents its about family and friends. He went back and said he stole the gifts and he was sorry. For christmas dinner he cut the turkey.
He was a bitter man he went into his past and saw how mean and nasty he was. A ghost told him he had to fix his life. Thats just what he did
He was bullied as a kid and sense then he has been alone his hole life.
