Don't take nice people for granted. We are all but humans.

I'm one you can push and push but eventually enough is enough. So don't take my kindness for a weakness. ~ Thomas Rubenstein 

Watch out for those 'wind up merchants' who enjoy keeping on pushing you to see how you'll react, for their own personal entertainment! They seriously lack maturity & compassion. ~ Elizabeth Nesterenko 

If we don't draw boundaries, we end of burning out in the end. ~ Linda Brooks
