I retire to bed at 3 a.m., answer the phone at 5 a.m. to a distraught female voice, and subsequently lie awake until 7 a.m. having been told that she'll call me back; which she then does. I further postpone a much-needed respite to comfort her during the course of the next half hour and, consequently, oversleep to the tune of 3 p.m., missing two lectures in the interim (ones which I would otherwise have attended). When she is incommunicado for the remainder of that day, I duly forego several hours' reading for a tutorial scheduled to take place the very next afternoon in order that I might be 'there', in anticipation of her return. Involved, much?
Maybe, I am a fool; but, maybe, there are some risks that one can't afford not to take.
