I am a nurse and want to say thanks to all the folks who made positive comments here.
On a daily basis I have someone complains to me about not getting what they want when they want it, and I wonder why I do it. But then every day someone says thank you, I don't know what I would do without you.
I tell them that every time I see someone sick, I remind myself that 'there but for the grace of God...' If I were a patient, I hope that some nurse will feel the same way I do, call it karma, or whatever, but it is easier on the spirit to be nice and to care about people.
