Answer:
Trevor Noah loves Christmas at his father Robert's house because it was so much different from the usual African Christmas that is only church service and dinner while his father's side is a European Christmas with all the fake snow, presents and Christmas tree etc.
Explanation:
Trevor Noah is an African-American born out of an illegal relationship from a black mother and a white father during the Apartheid. His unconventional birth and upbringing eventually influenced him a lot, becoming the main topic of his comedian jokes and even his memoir "Born a Crime".
Robert Noah is the father of Trevor, with whom Trevor's mother Patricia had him. Though Robert is a German white man, he had no interest or hatred of the blacks in Africa. He was simply indifferent about the whole Apartheid policy. And it was this that led Patricia to trust the man and have his baby. And while growing up, Trevor would spend his Christmas with his German father at his house, a European Christmas, much different from the African Christmas he would be having.
He liked European Christmas better with all the fake snow and presents and Christmas trees while an African Christmas usually involves just church service and dinner.
