The Absent Minded Nature Of Transitional Regret

 In an attempt to make sense of all that had transpired she sat down with a notebook and wrote out everything she could remember about the affair, from the first day of their acquaintance until the morning she woke up alone.

It didn't work. 

Despite rewriting the two and a half pages that covered what she considered the "crucial episode" three different times, she still could not explain, to herself nor any other person, what happened.

Story of her life, she mused internally - she meets people she considers perfect, and days or weeks or even months later they reveal themselves to be the exact opposite.

All the while she herself was, of course, without fault.
