I see this problem a lot amongst my married friends.
They complain about how their men seem so clueless about handling stuff like this. It's like they need a reminder to call to make an appointment as well as a kick in the pants to do something that was asked of them a week or a month ago.
One friend's hubby called her at work in a panic because he didn't know what to pack his son for his lunch that day. What the hell....???!
I think there are certain men who either prefer to be taken care of like when they were younger or are just too damn lazy and know instinctively that whatever they do not do, their wives will. I highly doubt any man is as clueless as he portrays. Sorry.
For your hubby, I say he deserves a kick in the pants. He knows he can do these things, he just wants to outsource them to you because it makes his life easier.
