re: 7:00 am on a Saturday. Do you cut grass?

My elderly neighbor and I made a deal that he cuts the grass (riding lawn mower) and I edge, clean up what he can't get to and blow the clippings off the sidewalk... So I have the more labor part and that's fine. But during the heat of the summer I want to start earlier. But he wants to have his coffee and I guess take a shite before cutting. This last summer was hard with that damn heat wave. We were starting at 8AM and be damned if the other neighbors were pissed. I am not as young as I used to be and had to take a break or two...
