"See any difference in those two Guest TIA???"
Not really.


Do you see any differences in my list of words above?

I will give you a hint. Half are synonyms for acceptable. Half are synonyms for justifiable. Now since you are so keen on the detailed difference between the two, go sort them out. If you truly have a consistent point, you must agree with half, and disagree with the other half. I am not putting words in your mouth, I am trying to understand the jumble that actually does come from your mouth.
