What is it that draws extreme emotions from people about staying alone? 
You meet scores of people who love the idea of staying alone with no responsibilities, no dependants , no-one to push you around, nobody to fight for the TV remote.......and on the other extreme you have the need for companionship, the need to be wanted, appreciated.
Is it a gender issue? 
Some would say yes, considering the fact that the males tend to be less endowed with the 'parallel brain'....but still..is that the case?
