I've heard several people lately, coaching clients, colleagues and others, express their disappointment when others do not thank them for work they’ve done or for kindnesses they’ve offered. It’s reminded me that I feel this too from time to time. Disappointment, in my view, can be a clue to us that our expectations have not been met. So an insightful question to ask ourselves when someone doesn’t say thankyou is: “What was I expecting?” and maybe also: “How were they to know?”.
