people are always sleeping on the train. just the other day i was sitting on the train and the guy next to me dosed off and started soring...i could not help but laugh-i mean hello you are on public transport....another habit people have on the tubes is picking their nose, it's so gross!!! i'm so amazed at the fact that people pick their noses in public...i mean you can be staring someone down while they have their index finger merged up their nose and they still carry on digging for diamonds like there is no tomorrow.
