If you’ve had your eye on a colleague all year, the Christmas office party is the perfect time to act on your feelings and try to get with them. When talking to your crush be aware of how they stand, how they use their hands and when they sip their drink. Once you’ve watched them for a while, begin to subtly copy their movements. Do not mimic their every move though. If you can do this successfully they will think you have a strong connection and be more likely to join you under the mistletoe.
