Christmas Jones

Only 2 people live in this house: me and my boyfriend.
Only 3 people have bought the presents under the tree: the two of us, and some small things from my mom.
Every day Tim asks me if we can open a present. He's been asking me since the first one appeared two weeks ago.
He shakes the presents like he was 7.
He shakes the presents for me.
He even shakes the presents for me that he wrapped himself.
This is totally killing him.
