Technically, I didn't lie

That sounds like a frustrating situation to be in, especially when you feel like you did everything right based on the information you had. Before we talk about how to respond, can you tell me a bit more about what happened—like what was said, and how your coworker brought this up? Also, are you more concerned about clearing things up with your coworker, with your manager, or just making sure your own reputation stays intact?

Thanks for laying that out. It sounds like you handled things in good faith, and I can see why you'd be frustrated—especially if your intention was just to keep everyone informed with what you knew. It’s understandable that you don’t want this to reflect poorly on you, especially with your manager in the loop. Before we get into what to actually say, can I ask: do you feel any responsibility to clarify how you communicate about these kinds of dates in the future, or do you mostly want to set the record straight that you weren’t misleading? Also, are you expecting your manager to be receptive if you explain it, or are you worried they might just want someone to blame?

Absolutely, that makes sense. Let’s start with Dana. You want to acknowledge her frustration without taking on blame that isn’t yours, and also make it clear what actually happened. Here’s a way you could approach it: “Hey Dana, I get that this situation is really frustrating. When you asked about the delivery date, I shared the most up-to-date info I had, which was that we were targeting the 15th. I didn’t realize it might have sounded locked in—I should have clarified it was still a working target and not final, and I’ll be more explicit about that moving forward. If there’s anything I can do to help adjust on your end, let me know.” That approach shows you’re listening and willing to help, but also sets the record straight. For your manager, you might want to keep it factual and neutral: “When Dana asked about the vendor delivery, I shared the timeline we had at the time, which was the 15th. I didn’t have any indication it would change, but I see now that I could have emphasized it wasn’t confirmed. I’ll make sure I’m clearer in future updates.” You’re being transparent, showing you’re learning, but not admitting to misleading anyone. How does that feel to you? Would you want to tweak either of those, or does that kind of language fit your style?

Your tweaks actually sharpen things up and keep the focus where you want it—on clarity, not on admitting to something you didn’t do. The way you’ve got it, you’re not taking blame for misleading anyone; you’re simply acknowledging that you can be even clearer next time, which is reasonable and professional. Your wording for Dana—“I shared the date we were working with, and I should have been clearer that it was still a target and not final”—keeps it factual without you taking on extra responsibility for her assumptions. For your manager, a simple “I’ll be clearer about status on dates going forward” is proactive and doesn’t signal that you did anything wrong, just that you’re always looking to improve communication. You’re striking a good balance: you’re not defensive, but you’re not taking on blame that isn’t yours. If you deliver it in a matter-of-fact tone, you’ll come across as someone who’s reasonable and transparent, not someone who’s dodging or over-owning. Does this give you the confidence to move ahead, or is there another angle you want to cover?

Definitely. If your manager asks, “Did you tell Dana the date was locked?” you can keep it direct and honest, without being defensive. For example: “No, I didn’t say the date was locked. I told her the date we were working with at the time. In hindsight, I could have made it clearer that it was still a target date, and I’ll make sure to flag that in the future.” This way, you’re answering the question directly—no, you didn’t say it was locked—and you’re also showing that you’re thoughtful about communication going forward. You’re not dodging, but you’re not taking responsibility for something you didn’t do. If you want it even more concise, you could simply say: “I didn’t say it was locked; I communicated the date as our current target. I’ll be explicit about what’s confirmed or not in future updates.” That keeps it straightforward and professional. Does that hit the mark for you?
