Percy stared at the twins' letter for several moments, examining the underlined bits and capitalized letters. He wasn't surprised that they assumed he had more important things to do than spend time with his family, but to send him a letter on his birthday pointing out his inadequacies (not to mention expressing desire to see Goblins wearing his underwear on their heads) was fairly cruel. Cruel but deserved, a voice in his head told him.
He folded their note back up and banished it to a nearby cabinet drawer. The present was still lying on his table, and he wasn't sure he wanted to open it. Knowing the twins, it was probably a booby trap.
Perhaps he'd wait on that, he decided. If it started smoking within its maroon packaging, he'd get rid of it. If not, he might chance to open it later. He was a Gryffindor after all. And a Weasley.
