Many men just think they know best. They think us wimmin are a bit inferior, and they think they can do everything better than us. And they do NOT like it when we do something better than them, or achieve something better or bigger. Puts a dent in their big manly ego. 
My DH does 'low level' shit like this. As a pp said, from complaining about groceries being put in the 'wrong bag,' to adjusting the way I have shut the curtains. I don't care anymore. When I shut the curtains now, I say 'there you go, I've shut the curtains, d'ya wanna get up and adjust them?'
Same with putting stuff in the trolley on the rare occasion we do the food shop together. (Once a month maybe.) I put something, in the trolley, and he almost ALWAYS 'adjusts it.' So again, I put the box of cereal into the trolley and say, 'there ya go, just move the box to the part of the trolley where YOU want it to be...'
He just looks blank, and sometimes doesn't even bother adjusting anything, as I am basically taking the piss out him, without being nasty, and he doesn't know how to react.
When I reverse the car up the drive, he sometimes even goes out and moves it, as I 'parked it too close to the public footpath...' (It was 6 feet away, and he moves it up a foot!) 
As I say, it's the whole men think they know best bollux. I don't care anymore, and as I say, I just take the piss out of him now. I do have occasions when I get really angry (if I am in a bad mood,) or even just snippy, but 90% of the time I let it wash over me, because whilst he thinks men are superior to women, I KNOW women are superior to men.
