Oh, Des! Dear, Des! You need the Hawaiian volcano goddess Pele. Pele was just like you! She loved her solitude, which was convenient because when you are incarnated as a volcano people know to give you your space. But, from time to time, she liked a little company so she would take a husband or hang out with her sisters. Sadly, in the struggle to find that balance between alone time and family time--she sometimes had to burn her loved ones to a crisp.
You see she was an artist! She created whole tropical islands that people literally call PARADISE, and sometimes her family just totally gave her grief so she had no choice but to lava them. It was a conflict.
What we really need to do is find that difficult balance between having our creative, alone time and yet not feeling the need to set the house on fire. Hmmm. How to do that?
Here's my idea: Tell your children that, in your need to find total creative expression, you will now be writing naked. Trust me: They will give you your space. As for your husband...maybe you should get a lock.
