Grammatical corretness is very important, but it's relatively minor compared to the value of the substance of what is said.
The only time that grammar really compromises the value is when it undermines the meaning, and makes it difficult for listeners to understand what is being said. In that case, correct grammar is essential.
Since you understood me, and most people did, minor grammatical flubs (especially in conversation) are of little significance.
It's not like if I was extra mindful of that, I could charge $ 5100 a day. My clients don't pay me for that, sorry.:-)
I beg to differ, HItmanNY. Grammar is extremely important - especially in the professional and academic worlds.
No big deal. Peace.
OK, now, let's all GIT JIGGY WID IT!
