We used to do that all the time... pretty much weekly a whole thing of fruit or veg or bread or yogurt or something past it's use by date and getting smelly would be chucked in the bin.
When I was home on ML and I had more time to think about home stuff, I looked carefully at what we eat weekly and that started the less waste, less spend on our groceries.
Speaking of being at home... it's interesting because I've commented on a thread on MN about this woman who wants to give up work and be a sahm and I know a friend in America who is thinking of the same... it appears to be for similar reasons but I don't know the whole story of the MN person. Anyway, my friend in the US is saying she's just tired of being exhausted all the time from working and wants to "relax" more and be at home (she has 2 dc 1 in half day K, one is a toddler). It would mean serious cut in their income and they would also have to move to reduce their living costs as necessity. She's quite used to spending as she pleases as well and would no longer be able to do this. She said she doesn't mind and just wants to have a "break" from it all and be a sahm.
I keep saying "just do what's right for you and your family" but I feel like she's going to very very quickly realize that being a sahm isn't about "relaxing" at all! She's still going to have to get older dc to and from school each day, entertain toddler, do housework...etc. AND to make it worse, her dh doesn't want her to do it and is stressed about the financial implications... this isn't good either.
Much like the thread on here, she thinks she'll also get a part time minimum wage job in the evenings, say, 7-12 or 6-11 a few nights a week. I don't think she realizes how tired she's going to be after a day of looking after dc!
Obviously, I can't say anything because it's a personal choice, but once she does it she can't un-do it as jobs aren't that plentiful at the moment. I just want her to THINK about this carefully and then if she still wants to do it, then do it. But I just think she's wanting to stay home for the wrong reasons... it will not be a relaxing fun life and they will be very, very financially stressed as well.
Would you say anything? She's a friend I've known since we were 5 if that makes any difference. We can say anything to each other, just this is so sticky.
