A helpful reader pointed out I don't really know Klingon.
PS. I just checked out your blog (very nice by the way, lots of stuff I need to read) and I noticed along the top of the page you have (jItlhInganbe') for "I'm not a Klingon". The translation your looking for would be (tlhIngan jIHbe' - I am not a Klingon).
Thanks, fixed it :) As I said, I'm not a Klingon, and had a terrible time finding something to work for "am" in The Klingon Dictionary or one of the on-line lessons I found.
Although that's kind of like one of those odd things that always strikes me as funny when traveling.
Me: "Can you tell me where a good restaurant is?"
Native: "Sorry, I don't speak English". (Sometimes even without an accent)
Hmm. I'll continue to have to rely on others for Klingon translations :)
