I love my parents but when I just visited them recently, I turned to a puddle of tears when my father made some comment that he was irritated about me drinking a lot of water so much. I mean the way he said it was mean, but parents seem to know the exact words to rip us to shreds.
I'm sorry that happened, I am an RN too and if they implied that I didn't actually know what I'm doing, I would be upset too.
