Cauld kail het again is aye pat tasted.
Cauld kail het again, that I liked never; auld love renewed again, that I liked ever.
Cauld parritch are sooner het than new anes made.
Cauld water scauds daws.
Chalk's no shears.
"Taken from tailors marking out their cloth before they cut it, signifying that a thing may be proposed that will never be executed."—Kelly.
Change o' deils is lightsome.
Change your friend ere ye hae need.
Changes are lightsome, and fools like them.
Changes o' wark is lightening o' hearts.
