Then there are the passengers. I've noticed that if you go south of the river there will invariably be a woman who sits behind you and talks on her mobile phone loudly in her native tongue, without cease, from when she gets on the bus to when she gets off. I find this confusing. Seeing as this woman does not pause for breath for even a second, I wonder what is going on at the other end of the phone. Either the person she is talking to remains completely silent or they too are talking without stopping. More disturbingly, I wonder if perhaps there is nobody on the other end at all. This would explain why she can talk at such length: otherwise I'd like to know what her payment plan is.
