I have often sought time alone. I am an introvert on the Myers-Briggs scale. I need to pull back to reflect on what is happening. I cannot make decisions while I am interacting. I always need to think things over by myself.
Extroverted personalities think best in the midst of action.
I believe the Myers-Briggs personality testing of recent years has been a very helpful innovation to let us understand each other and our differing needs. Some people will more naturally yearn for sabbath time than others. Over the years, I have taken a number of solo trips and retreats. I have a deep hunger to pull back to reflect, really, to digest things that have happened to me. At the same time, I have experienced painful loneliness when I do this.
