I don't know what French girls are like when they're nervous This is just something that came into my head, and I realized I'm not quite certain how to translate it. I was thinking: Je ne sais pas comment soient [ou sont?] les filles françaises quand elles sont nerveuses. Does the subjunctive work here? I can think of other things I could do, like replacing the verb être with another, or rearranging the syntax, but I really want this kind of construction to work.
