"We would prefer to not work together."
Translation:On préférerait ne pas travailler ensemble.
This lesson brings forward one of my biggest gripes with Duolingo; they refuse to explain the reason or the rule behind the grammar. I get that the method is, as they say "to learn by making mistakes" but at some point, my mind fails to hold so many examples by rote memorization (age has its privileges and its costs). More importantly, I learn better by understanding the principle behind the choice of words, and then applying it.
Thank you for your patience, I know none of us here can do anything about this but I needed to vent; this is really getting to me today.
You can always study outside of Duolingo. You can quickly find resources on the internet that explain everything we learn here. Use your search engine for "French conditional tense" or "on vs nous ", or whatever is confusing you.
And of course, if you could pose your specific question here, other users would be happy to explain it. Then you could pay it forward by helping someone else in a future lesson.
