Taken for a ride

I love travelling in the country, but I don't like losing my way.
I went on an excursion recently, but my trip took me longer than I expected.
'I'm going to Woodford Green,' I said to the conductor as I got on the bus, 'but I don't know where it is.'
       'I'll tell you where to get off.' answered the conductor.
        I sat in the front of the bus to get a good view of the countryside. After some time, the bus stopped. Looking round, I realized with a shock that I was the only passenger left on the bus.
        'You'll have to get off here,' the conductor said. 'This is as far as we go.'
        'Is this Woodford Green?' I asked.
        ' Oh dear,' said the conductor suddenly. 'I forgot to put you off.'
        'It doesn't matter,' I said. 'I'll get off here.'
        'We're going back now,' said the conductor.
        'Well, in that case, I prefer to stay on the bus,' I answered.
