AIBU or is DH a bit unusual?
He's a fantastic husband in many ways - kind, always means well, works very hard, very financially minded so takes care of that side of things. I can't fault him there. However, when at home he is focused on two areas and that's it -
- The lawn. Even if the house was a bomb site, he would ignore that and just step over the mess, but if there is a single item on the lawn (e.g. a sock), he will be out there like a rocket, demanding to know who left it, when and why.
We have 3 boys under 11 and I am also "temporarily" looking after one of their friends after school until 6pm. Obviously, they're out in the garden in this weather and it's quite full on. I don't have the time or inclination to be tidying after them in this heat because I'm also doing dinner and generally dealing with them anyway. So DH is tending to make a fuss about the garden when he gets in and expects me to be bothered about it, but I think he should just let it go tbh. It is outside after all 
- Recycling. He is obsessed about reducing cardboard boxes and plastic containers into the smallest possible pieces so they can be stored most effectively in the recycling boxes out in the front garden. He has in average about 3 boxes from Amazon or whatever coming every day, containing bike stuff and all kinds of wires, as well as larger items like wheels. It blocks the hall so I put the stuff in the garage (aka his bike workshop) for him and then flatten the boxes as best I can and stuff them out the front. He thinks it is inconsiderate if me to leave this cardboard visible to the neighbours and he goes on about about it as if I don't have other priorities or actually care. Related to this is that he has even built a kind of shed for the large wheelie bins so that they are not visible either
It's not the end of the world, but how can I get him the shift his fastidiousness over to a few other more useful and pressing matters in our daily lives e.g. clearing dishes away or laundry, that kind of thing? Tbh I don't even need him to do much around the house, but stop bloody nagging me about cardboard and things outside!
I don't think IABU, but any ideas welcome.
