"...........to be the Batman of your closed group of friends, only to realize, once alone, that you don't really like heights. Or fighting."

LOL! So true.

The time we spent alone not only allows us to put our thoughts together but it allows us to do so in manner that is true to ourselves. You are right when you say that without 'me time' we are doomed because in those moments we put everything that we have dealt with in the emotional processor.

Even when we need company or want to be with a lived one we need short breaks for the 'me time'.
