I remembered something today (don't ask me why because I haven't the faintes idea). It was a while ago, during a summer when the sun shone enough, or the rain held off enough, for me to go walking along the Thames path. I had gone a little further than I intended and realised that the railway station I wanted to get to was possibly more of a walk away than I wanted. I didn't even know if it was the same side of the river as me.

There were no signs (why should there be) telling me how far off the station might be, but there came a young woman, striding happily and not looking exhausted. So I stopped her and asked, 'Sorry to bother you' (I am a Brit after all, 'but could you tell me if the station is on this side of the river?' 

She put a finger to her lips as she considered the problem. Looked up the river and down, and said (in a lovely Irish accent), 'Well, I couldn't say. But I do know the bridge is on this side.'
