He runs to another room like Speedy Gonzales whenever someone calls him acting like an FBI agent working on a secret task. You also like to take some calls in private, but every time? It just seems wrong and unnecessary.
I remember the guy I dated used to always run away in panic whenever his phone rang. There was just something weird about it. One week later, guess what I found in his phone records? Dozens of calls from the same woman I never heard about.
