a new tradition

I'm the new boyfriend you bring home from school at Christmas.  Arriving late on Christmas day (cheap fares), I'm shown to the guest room, your old room, while you are to sleep on a foldout in the hall.  I lie on the bed awake, for not half an hour after the last lights are turned off, I hear the door open and you whisper, hello lover.    The bed is too noisy for us but we are quite able to satify ourselves on the floor.
