Sagittarius (Nov. 23-Dec. 22)
If you have a Sagittarius on your hands, don't be surprised if you're on the receiving end of the silent treatment every now and then. This fire sign is first and foremost known for their optimism but also tend to be unemotional when forced to react in a situation they're uncomfortable in. The bottom line? They avoid conflict at all costs, even if it means ignoring you for a while.
