I was just picking my dd up from gymnastics and one of the other mums was there who lives in my street.. We were chatting to a 3rd mum (I swear I'm getting to the point lol) who was saying that with her job she is massively behind on housework.. The conversation went something like:
Mum1: it's a never ending job
Me: don't worry about it, do what you can and the rest will catch up eventually.. Plus that's what sofas are for.. For hiding stuff under ;)
Mum2: oh I knew you were like that as you always have washing hanging up in your sitting room..
Me: dies of shame um it's ironing, it gets hung up there so dh can take it to work without blah blah
Mum2: oh does it change then?
I muttered some excuse about how I iron on a Sunday and then dh takes the clothes on a Tuesday to his job (works away)..
It wasn't till I got home that I suddenly thought that unless she stares in my house every time she walks past how the hell does she know?' 
I obviously need to start shutting my curtains.. And I put the ironing in the back room!
