Asking as we've just had yet another silly argument about hoovering!
Every single time I ask DP to hoover it very quickly descends into a barrage of excuses as to why he shouldn't do it.
Then it often turns into a full blown row where afterwards he sulks for hours.
I ask him about once a month. I hoover every week or two, so not that often.
Anyway, he's out sulking in the garden whilst I have a very large glass of wine 
The hoover has been abandoned in the front room..
