Enough?

This one time, I said I was a positive person and hopeful.

Grrrr.  Today is one of those off days.

I shouldn't let the negative asses around me drain my positive hopefulness...but it just makes me so angry.

No matter what, no matter how hard I try, no matter how positive or happy I am, there's always someone who never appreiciates, only points out the negative, is always fucking jerky. 

When is enough enough?
