Cultural Tip
French often prefers the ‘est‑ce que’ construction for neutral questions because it avoids inversion, which can sound formal or literary. With reciprocal verbs like se rencontrer, remember that the past participle must agree with the subject (rencontrés for a masculine plural group, rencontrées for a feminine plural group). In spoken French, the liaison between ‘rencontrés’ and the question mark is usually dropped, but the written form keeps the final ‘s’.
