Think nothing of it. Ce ne rien, if I remember my Francais de l'ecole secondaire at all. And that is probably quite flawed.
Another thing I like is hearing people whose English is secondary, speak it.
I write screenplays, (no big deal), and I am sensitive to dialogue.
What I like is the way these people will often carefully speak and give really interesting and expressive emphasis to the words and phrases. Almost like their speaking English is actually preferable to the mumbling of native speakers.

Uh...c'est ne rien ?
