I am totally baffled when people use that expression. Does it mean that whenever you do not use "to be totally honest," it means you are not telling the truth? Lying about something in other posts?!?!?!?
Otherwise, what do the words mean?..why use them?...makes me suspicious.
you're right, one can not be "partially" honest. Nevertheless it is something that is often here used in Italy.
What I mean is that after getting to experience something that I didn't before ('07 Drake Pro) it would not be honest not to amend my previous suggestions. Even if I was honest when I wrote those suggestions, and I could as well avoid to add that last post.
