It would be classed as an admin duty in our house...and I'm supposed to be in charge of admin now I don't work........However silly DH didn't ever see my desk at work.....if he did he'd know not to rely on me......my filing is always a good few months behind and I alway pile it up and then have a blitz....so I think maybe I'm more like your husbands!!!
DH is pretty useless at birthdays, anniversarys, anything with a date....I think we're as bad as each other.
In our house, if you want it to get done, do it yourself...as we're both useless!
