Had this picture taken some thirty days ago, thought I could use it to represent solitary. I was assisting my supervisor standing in the front of the hall in the first lecture of the semester. Most of the course participants were still undergoing registration procedure, so only a handful turned up the first day. One of those present came along with his son (standing at the back of the class, where I was seated). Unattended, alone (without  any peer), idle but energetic, he hops from one row to another. He finally got work to do. He began folding the untaken tables. When he was done, he sat quietly apparently thinking out the next task (all by himself)
