like you just intuitively know what's appropriate to say and what isn't.
/laɪk ju dʒʌst ɪnˈtuɪtɪvli noʊ wʌts əˈproʊpriɪt tu seɪ ænd wʌt ˈɪzənt/
只是直觉地知道什么该说，什么不该说。
there is this underlying agreement.
/ðɛr ɪz ðɪs ˌʌndərˈlaɪɪŋ əˈɡrimənt/
这是双方达成的共识。
and now it's not always obvious you know finding that balance between showing interest and curiosity about a person without being intrusive and overstepping a boundary.
