「またいつかぜひ」って言われたら、実は断られてることが多いんですよ。 — When someone says 'let's definitely do it sometime,' it often actually means they're politely saying no. (Cultural · Communication, Casual — to friend, JLPT N3)

Gesture & etiquette

A knowing, gentle smile when sharing this insight — you're letting someone in on a cultural secret. Avoid making it sound negative about Japanese people; frame it as a system designed to preserve everyone's dignity.

This is the classic 本音と建前 (honne to tatemae — true feeling vs. social face) phenomenon. In Japanese culture, a direct 'no' risks causing embarrassment (恥) for both parties. Phrases like 「またいつか」「考えておきます」「難しいかも」are often polite rejections. Context and tone are key to reading these correctly.
