The conversation you keep avoiding doesn’t shrink. It gets bigger every week you wait.

Avoided conversations do not hold still. Each week you wait adds the original subject plus the fact that you said nothing, and the second part eventually becomes harder to explain than the first. What began as one awkward five minutes turns into a position you have to account for. Delay is not neutral, it charges interest.

Name the conversation and the earliest hour you could reasonably have it. Open plainly, without a long preamble, and get the subject into your first two sentences. It will be smaller today than it will be in a month.
