When directed towards a 4yr old child on her way to school. Because:
- Presumably she isn't allowed out alone anyway.
- She was only kicking a conker along the pavement.
- If he grounds her for kicking conkers what does that leave him when she is 13 and starts smoking (or worse).
I would have assumed he was joking, if it wasn't for the tone of voice and the fact that he looked so cross.
