Your analytical side goes out the window now, and you're indulging in sweet sentimentality and the joy of the season. It doesn't hurt that you have the day all planned out (which will also come in handy since if you had to make a decision today, it'd be difficult). Enjoy the company of family and friends, and don't be surprised if you're moved to tell people how meaningful they are to you. In fact, just go ahead and do it.
