I think every employee everywhere sees themselves having a "lazy day" in their job from time to time. You just aren't feeling it, want to put the mental crockpot on simmer and coast to 5 o'clock. That is incredibly human and normal.

You are given this wealth of days off ( 34, including the 9 holidays) with no real restrictions on when to use them. You would want to use one of these that day instead of pretending to be productive. Use your time to pull into the mental pit-stop and disconnect for the day, officially, as opposed to pretending.
