Perhaps I'm as bad. There's a chap hammering away on a laptop a few rows in front of me, another chap who just got off at Hillingdon who was working the whole journey here. Others working too.
What is that kind of life like? When they get home, do they have mental energy to think about love, laughter and life or are they consumed by planning the next day's work? Perhaps they get lots done on the bus, so they can leave the office early? Are occupied minds less likely to have time to think troubled or troubling thoughts?
So many unknowns, but watching people is fascinating. If I could blag and bluff the funds, it would be interesting to do this journey every day for a year and write about the experience.
