Leaving Town

They say every picture tells a story, but not quite sure what this ones telling.
Maybe the woman is thinking did I buy washing up liquid, bread, butter, or even oven scourers.
Or maybe she's thinking 'did I bring a bag with me'?
On the subject of bags its not often that you come across people who've been out shopping not carrying a plastic bag, ghastly things! as they always seem to spoil a picture.
