To mow the grass?
We have a very quiet electric mower. And most mornings there are delivery lorries/vans making a racket at 8 (the whole street seems to be extending their house atm, we have a builder's lorry almost every day and they always come early).
The sun is on the back garden until gone 6pm, I work until 2.30 and by the time the grass is in the shade I'm frankly knackered.
Would it really BU to give it a quick mow at 8?
