I'll let you know

Neutral Depends on context

What it really means

Sometimes genuine, but often a soft way to end the topic without committing. After job interviews, "we'll let you know" with no timescale is sometimes a gentle no. Silence is usually the answer.

Chinese explanation

有时是真的会回复，但常常是不作承诺、就此打住的委婉说法。面试后一句没有时间表的"我们会通知你"，有时就是委婉的拒绝。没有消息通常就是答案。

Example conversation

A：你来参加知识竞猜之夜吗？ B：到时候告诉你。 A：那就是不来了呗。
