I used to hear the same excuse from my DSD's... 'oh sorry, I forgot'... oh how I have learnt to detest that empty apology!!

So now, if they are at home while I'm at work and I need things done, I write a list.

S - today you need to do at least 2 x loads of washing, hang out all washing, take off when dry. Fold all clothes.
T - today you need to fold the towels, empty the recycle bin, take out the rubbish.

When I get home, I'll go through the list with them. If it's not done, they do it then and there and let me know when it's done. In the mean time, there is no phone / internet / tv.

I completely agree with what you've done. It can't be one-sided. It's not fair. It is hard to stick to your guns, but it will definitely be a great lesson for her to learn. And it doesn't have to be done in anger, just keep calm and carry on about your day.

I like what Marydean has said too - these are basic life lessons you are teaching her. It's not a punishment, it's basic self-maintenance.
