What a lovely idea for a conversation! None of the elders in my family seemed to be much into sayings, except possibly the one who died when I was a baby. So one that has stuck with me actually came from television that Gwyn and I watched ages ago, a discussion about wise cooking advice from mothers. Our favourite was "If it's from a mix and you mix it yourself, it counts as from scratch." I also use "buy cheap, pay twice".
My Mom always said " if you have a job and want to keep it, you will neglect your Housekeeping to rest up for your job". Or, in modern English, if you want to have enough strength to get up and go to work tomorrow, you will skip the housework and get some extra rest. However, I never listened, LOL!!!
My grandfather told me; "Marriage is 90%/10%. You give 90%, they give 10%. If you both do it things work out."
"Never trust a skinny cook"!!!!
