Today I finished reading the book my friend-turning-enemy had given me. It was very realistic. It captured splendidly the quarrel scenes, how minor frictions escalate into irreconcilable enmity. It is a very unpleasant read if you immerse too much.
Also I noticed that interspersing reading into fragmented leisure time dilutes the fun in reading. In the end, I just set aside a chunk of time just to read it and then when I finished I felt as if that I had woken up from a long dream.
