When Is Sharing, Whining?

A friend of mine  mentioned that my blog recently has gotten whiny.  I read it over, and I don't see any instances where I'm whining but perhaps my tongue-in-cheek, self deprecating humor sounds whiny.  Whining is not my intent, and so many times in blogging (or even writing anything really at all), I can be thinking of what I am saying one way  (think sarcastic, acerbic or biting)  and it can be perceived as another (whining).  So if my writing has come off as whining it was not meant that way.  I have actually been really cognizant of what I post and say, because well I am out of a job and it does suck but this blog is not a "lets sit around and have a pity party" blog.   But, it made me think-  when is sharing simply sharing, and when is it whining?  If I talk about how sore I am, is that sharing in my daily experience or is it whining about how hard it is?  What is the line that divides the two.

We all have days when all we want to do is sit and complain but how do you tell when your "one day of complaints" has morphed into three, or five, or a month?

I'd love to hear your thoughts!
