Keep your mouth shut and your een open.
Keep your tongue a prisoner, and your body will gang free.
Keep your tongue within your teeth.
Kenn'd folk's nae company.
Ken when to spend and when to spare, and ye needna be busy, and ye'll ne'er be bare.
Ken yoursel, and your neighbour winna misken you.
Kindle a candle at baith ends, and it'll soon be done.
Kindness comes o' will; it canna be coft.
Kindness is like cress-seed, it grows fast.
Kindness will creep where it canna gang.
