Herry smiled to his friends, ready to leave so he could get back to the Dursley's, only to halt when a small hand tugged on his sleeve.
"An early birthday present, Harry." Mayumi smiled mysteriously as she winked and shoved something small and square into his hands, "Don't let them find it."
When Harry got back into his room, he was pleasantly surprised to find a phone just like Mayumi's with a small note of 'call me' stuck on it.
