Actually, I've got an idea, dickhead. It takes absolutely zero knowledge to nitpick typos and snipe from afar. One quick Google search and you can double check any foreign phrase. I'll wager that you looked at what I wrote, and didn't know what it meant, did a Google search, found the mistake, and then, being so clever, took a snipe.
So, how about you post a few sentences in French, and I'll respond in like. Although I never claimed fluency in that language (I'm conversational), it might be entertaining to see you squirm.
I expect utter silence from you, for as we saw in the discussion of comparative educational credentials - you are great at attacking someone whom you do not exceed by any measure.
And I close with one more FOAD.
