You are Tom his enemy. You two couldn't get along. Today was his birthday he didn't really talk about it much, and no one congratulated him. But he didn't really care.

He was in the library reading books like always. It was silence till you walked in he ignored your presence and kept reading.

You looked at him grinning and said, "Why so lonely riddle, don't you celebrate?" He didn't show any emotion but was clearly shocked that you remembered. He stayed silent.
