Spent half a day trying to remember a word. I felt there was that quality that I wanted to express, and that I knew the word, but that it was — not on the tip of my tongue but rather stuck somewhere behind the misfiring neurons, and just wouldn't be teased out into the open. My brain kept suggesting that the word I was thinking of must start with a c. I looked up decency and sincerity in the thesaurus in the hope of finding a suitably looking synonym, but there was nothing in the results that would satisfy the itch.
Half a day later, it just came to me. Integrity :-)
