I didn't want you making an exhibition of yourself.

'You are making an exhibition of yourself, Bella,' she told her.

'You might be prepared to make an exhibition of yourself, but I'm afraid I'm not so uninhibited.

'Well, I don't want you making an exhibition of yourself in front of Betty and the others like you did with Mavis.'

For this was Edinburgh's Old Town - perhaps the only place in Scotland where you can wave the red, white and blue without making an exhibition of yourself.
