Yesterday, Anna defined the seven types of Tube/train smile. I experienced two further types on my southbound Northern Line journey home tonight, taking the total to nine.
The "Ah, finally! smile"
This is usually a reciprocal smile given after an event has taken place before which there was an inordinate delay. This could be an announcement about the reason for a delay, or as in today's scenario, the Tube train finally moving after being stuck mid-tunnel for ten minutes or so. Myself and a female commuter gave each other a wry smile which said "ah, finally".
The "I'm listening to a great track, outward enjoyment" smile.
This smile, sported by myself, lasted four minutes and six seconds this evening, the entire duration of Dexy's Midnight Runners' Come On Eileen. I think I'm quite rare in my outward display of musical enjoyment.
