As a result of the travelling I have undertaken around the United Kingdom and Spain in the past year or eighteen months, I have come to some conclusions about the manner in which people, in general, commute, particularly in London and other efficiently-run cities and countries.
I tend to travel with one, small, cabin-sized suitcase, and have developed a particular style in which to walk with it, especially when concerning tubes, Underground stations, escalators, travelators and, perhaps most frustratingly, other people. You see, there is a way in which one should conduct oneself when you have luggage, and it is a way that only a few people appear to have mastered.
