No offence meant, Mkiss. I presumed you were using it yourself to describe a series of actions.
I am not feeling offended in this case - it was just a question whether I could be - so a question in language and grammar...

I think that the comma after "simple" tends to suggest that the person to whom it is directed is stupid. Whether it is a noun or an adjective is, I think, the discussion.
