Reminds me of an Girlfriend of mine I briefly dated who was on her First day at work. She was studying to be a Registered Nurse and as most of you know that you don't start out as an R.N. She like most, was a Certified Nurses assistant. Anyway she had to do her first sponge bath on an Older Distinguished Black Man on her first day.
As she washed and finally got to his Privates, She Said She was scrubbing and Scrubbing to make sure did her best, as this was her First day and she wanted to be thorough...
The Older Gentleman stopped her and told her "Honey, That's my real color, it's not dirt! And it does not wash off! And if you keep Scrubbing, there is gonna be a bigger mess to clean!!!"
