This a good debate. I live with worldly people (my family) and I definitely think that if you partake in holiday like activities with worldly relatives it can definitely be taken the wrong way. I have to be careful that what I do isn't confused for something else by my family. However, if you go to a party on January 1 with witness friends, aren't you just taking advantage of the day off from work? I definitely think this is a personal decision, but intent and the activities taking place are important to consider.
