Why me?

'Hello. It's (name with held to protect friend but why I should I don't know)Do you still clean houses?'
'Oh. Hi. No not really. Giving it up. Going to be a mega-star author.' (didn't say the last bit - was thinking it)
'I clean a house for someone once a week, but it's really filthy and it needs a good clean. Can you do it?'
'Me? Why don't you do it?'
'It's too much for me?'
'But it's not too much for me, then?'
'Well, it needs a really good clean.'
'What do you do when you go there?'
'Just wash up and wipe the kitchen sink.'
'How long are you there?'
'An hour a day.'
'It takes you an hour to wash up and wipe the sink? How many people live in the house?'
'Two.'
'Do a lot of cooking, do they?'
'No. Anyway. I can't do it. It's hard work. Can you do it?'
'No.'
'Why not?'
'Because if it's too much for you then it's going to be too much for me, too.'
'That's disappointing.'
'Sorry.'
'Are you sure you can't do it?'
'No.'
'Well gotta go.'
'Oh, so you're not staying to chat?'
'Something on the stove.'
'How convenient.'
'Bye.'

Point is: I know the house in question. I've seen cleaner cow sheds. It's abominable. The only thing that would clean the toilet would have to be something nuclear. It absolutely annoys me when people think I'm a) prepared to clean up anything. b) have the strength of an ox. They just see a filthy hole of a house and think what idiot can we get to clean it? And then get on the phone to me. Well. Take Note. Those days are over.
