Three days of solitude sounds like a movie or book title. An artist could make something of it; someone arrives to disrupt, a telephone call changes everything;, the main character disrupts her own solitude, or, three days of solitude prevails.
I’m doing my usual email correspondence, and my husband is with me—both fair game. Something from outside could disrupt me, and of course I could sabotage the three days. But I don’t have to do that. And yet, being an ADHD kind of person, it is always possible that I might just get up and unwittingly do something social. But I think not, because getting up a moving around what I need to do; it’s the social that disrupts my solitude, not my own physical activity. I’m on the alert.
