Probably yes but he's not doing it!
DP is just finishing his last nightshift of 3. He doesn't go to bed after his last nightshift, his choice as he then can't sleep at night.
I have been suffering horrendously with my hayfever over past few weeks, had about 9 hours sleep over 4 days.
I cheekily said to DP on phone earlier "oh I might go back to bed when you get home", he said "no I was going to cut the grass, you'll need to keep an eye on DCs"....what????
Admittedly our garden is like a jungle as its not been dry when he's been off for so long, but absolutely no way is he cutting the grass!!! If he had said paint the house, wash the cars, decorate the living room, fine, but cut the grass?? he's off for the next 3 days when dc's and I are at work/nursery.
Do you think he's trying to bump me off 
I should just point out that I wouldn't allow him to use machinery after his nightshifts anyway!
