That's understandable watermeadow, but you said it yourself - 'when there's nobody about'. So presumably the dog thieves aren't about either. I think I'd be cautious about my route, though, if it was me.
The answer, perhaps, is in taking up a quiet hobby that you confine to the early mornings. Yoga? Some sort of craft? Baking (without noisy machines, of course!) ? An online course?
I've got another 'keen'... Ouch!
What is a reasonable minimum spend for an online grocery delivery??
