Hand over all the letters except yours
From Create Your Own Story
Uncle Vernon grabs the letters from you. You tear open your letter. He tears open the bill, and snorts in disgust. Then, he flips over the postcard. "Marge's ill," he informed Aunt Petunia, "Ate a funny whelk..."
"Dad!" said Dudley, the sniveling brat, "Dad, Harry's got something!"
You are about to read the letter when Uncle Vernon snatches it out of your hands.
Then Uncle Vernon turned to your letter. He looks at it, and his face turns from red, to green, then to pale white. "P-P-Petunia!"
Then Aunt Petunia reads it. "Vernon! Oh my goodness - Vernon!"
You shout, "I want to read my letter!" Uncle Vernon asks everyone to get out.
