To say 'expect' it gives me the impression of a dominant husband who lays out the rules for the household and all it's members....and gives me the creeps as well.
He runs his companies outside the house, that's his domain, the meetings, the deals etc....But the house? That's my domain. He doesn't have to expect anything from me, I expect it from myself.
I expect that I'll feed, clothe and care for my children everyday while he's away to the very best of my ability, (although some days the clothes don't match and the lunch is waffles

) as well as keep things clean and somewhat tidy, to run my home business in a professional manner, to keep mealtimes interesting and tasty, and, out of respect for him and his schedule, make sure he has two clean black socks - not nessessarily matching - every morning.
And, if for some reason nothing gets done all day because of illness, schedule, etc, it's not a big deal, we order take out and skip the laundry.
Honestly I don't think we ever talked about it either....just kind of fell into what worked for us.
