I was wondering how a passive sentence like:
トムさんに話しかけられた。
Tom started talking (to me).
could be changed to express that it was the first time that it happened. My attempt was:
トムさんに話しかけられたのは、初めてだった。
Is it gramaically correct? ( Should 話しかけられる be in the plain form or in the informal past?)
Does it sound natural, or is there a better way to say it?
