So as a hygienist, people will tell you some crazy stuff. They think of you as their therapist. I don't feel the information train should go two ways. I prefer to not tell them every little detail of my life...
Some information I have heard mentioned that should not have crossed another hygienist's lips:
My chin hairs are long enough to braid. I need to remember to pluck them.
My period just started. I need to run to the bathroom.
I'm sure there will be more to add to that list as you never know what's going to pass through her lips.
