There are better things to do then getting into Christmas Spirit during the coolest time of the year. For example to go to the Beach! Especially when you find a part of the Normandy Crew there. Thane looks busy, but what (or who) does Liara see ?
P.S. Please don't remind me that Thane has not the chance to go to the Beach anymore... It's just sad.
