Be careful claiming to know personal details. I'm not knocking what you're saying about apparent mobile phone use, but maybe just leave it at that? Saying you know exactly where they live is going into different territory, it sounds sinister even when your intentions are honourable. Can you see where I am coming from on this?
Could you please stop being inconsiderate and stop parking on the zigzag lines whilst watching me taking photos of offenders? You're one of them and just add to the congestion/put children at danger.
OH if anyone's renting out their mouths I'd be interested .
