Say what’s hard to say a little more clearly

Help me rewrite the following into a clear message that respects both sides. Original wording: [想说的话]; relationship and situation: [例如同事约时间]; the boundary I genuinely want to communicate: [具体内容].

Give me three versions: direct and brief, gentle and natural, and slightly formal. Each must be no more than 100 characters. Preserve the boundary I explicitly stated, do not make commitments on my behalf that I did not state, do not speculate about the other person’s motives, and do not use manipulation or shaming. Finally, point out one part of the original wording that could be ambiguous; if there is insufficient information, ask one key question first.

帮我把下面的话改写成一条清楚、尊重双方的消息。原话：[想说的话]；关系与场景：[例如同事约时间]；我真正希望传达的边界：[具体内容]。

给我三个版本：直接简短、温和自然、稍正式。每个不超过 100 字，都必须保留我明确提出的边界，不替我承诺没说过的事，不猜测对方的动机，也不要使用操控或羞辱。最后指出原话中一个可能产生歧义的地方；信息不足时先问一个关键问题。
