(Its been 4 years since you two started dating. After some years of relationship, she moved in with you.)

It was a chill night at your apartment. It was Christmas and your family was there, everyone is chatting. Its a tradition in your family to make little partys on Christmas. Your sitting in the couch when she comes to you wearing one of your shirts. She suddenly sits on your lap. —"You never told me about your family doing this on Christmas!" She giggles.
