Overview
Someone is stepping into your territory today, but as threatened as you might feel by them, this is no day to engage in any kind of power struggle with them. You're better than they are in so many ways, and they are well aware of this -- which is why they are making such aggressive moves. But their tactics are only going to backfire on them, so you don't have to worry about reprimanding them. They just want to bring you down to their level. Don't go there.
