Pleeeeeeease

'Let me have that dog treat you are holding just above that camera lens.'

No, not yet - and stay still you silly dog.

'Oh but pleeeeeeaseeeeee'

No, and stop wriggling, the light is going, the shutter speed is already dropping too low and I do not want to increase the ISO any more.

'But I have been so gooooood'

No you have not, and you stink like a dog. Why does your nose stick so far out away from your eyes? At this wide aperture (f2.8) the depth of field is too narrow to get your stupid nose in focus, and I do not want a smaller aperture as the light is fading fast.

'Hurry up you daft idiot. It is freezing sat here, you stink like a human and have abandoned me all day to guard the house... Now give me the sodding biscuit!'
