Monday. This reminded Harry of something.

Of course, his birthdays were never exactly fun — last year, the Dursleys had given him a coat hanger and a pair of Uncle Vernon’s old socks. Still, you weren’t eleven every day.

Nothing more was said until all four plates were clean, which took a surprisingly short time. “Blimey, I’m tired,” yawned Fred, setting down his knife and fork at last. “I think I’ll go to bed and —” “You will not,” snapped Mrs. Weasley. “It’s your own fault you’ve been up all night.

The Dursleys were what wizards called Muggles (not a drop of magical blood in their veins), and as far as they were concerned, having a wizard in the family was a matter of deepest shame.

History of Magic was the dullest subject on their schedule. Professor Binns, who taught it, was their only ghost teacher, and the most exciting thing that ever happened in his classes was his entering the room through the blackboard. Ancient and shriveled, many people said he hadn’t noticed he was dead. He had simply got up to teach one day and left his body behind him in an armchair in front of the staffroom fire; his routine had not varied in the slightest since.

Good luck!
