Chaff and grain together

“Oh, the comfort, the inexpressible comfort of feeling safe with a person, having neither to weigh thoughts nor measure words, but pouring them all out, just as they are, chaff and grain together, certain that a faithful hand will take and sift them, keep what is worth keeping, and with a breath of kindness blow the rest away.”
― From "A life for a life" (published in 1859) by Dinah Maria (Mulock) Craik
