At work it can get you into trouble if even an unattractive female wants your job, to even a score, or money from your company...
For very practical reasons, the Pences are protecting themselves, together or alone, from the scandal mongering press as well as political intrigue. The Pence marriage and togetherness is genuine aside from practical considerations. The one scene I remember from the Trump inaugural balls was of the Pence family dancing along with others on the stage. Mike Pence and his wife were so proud of their family, and the whole demeanor of Mike Pence could be described as almost bursting with love and pride for his children and wife. He was totally oblivious to the other personalities around him. This atmosphere that the Pences carry with them takes years to develop. They have genuine love for each other and family. God bless them all.
