Thomas:
You always leave milk and cookies out for 'santa' of course Thomas always came down in the middle of the night to eat the cookies and drink the milk.
Newt:
Every Christmas Eve the two of you drink hot chocolate and open one present each. He knows how excited you are and can't resist letting you open at least on present.
Minho:
You two always watch the movie White Christmas. It's a classic, and you two love cuddling on the couch and watching it together as you quietly sing along to the songs.
Gally:
The night before Christmas you two make gingerbread houses. He always loves eating some of the supplies no matter how many times you tell him not to.
