how long has the grinch hated christmas

The Grinch has been a resident of Whoville for many years, and he has hated Christmas for just as long. He has always resented the holiday's emphasis on gift giving and merrymaking, and he feels that it is a pointless and wasteful tradition. However, his hatred for Christmas is more than just a general dislike of the holiday - it is also a deep resentment for the Whos' joy and happiness, which he sees as an affront to his own misery.
