On Christmas Eve, Harry went to bed looking forward to the next day for the food and the fun, but not expecting any presents at all. When he woke early in the morning, however, the first thing he saw was a small pile of packages at the foot of his bed.
"Merry Christmas," said Ron sleepily as Harry scrambled out of bed and pulled on his bathrobe.
"You, too," said Harry. "Will you look at this? I've got some presents!"
