My eyebrows are light, so light that they are almost invisible.

Once I went to get my eyebrows tattooed, and the tattoo artist asked me to lie down. She shined a light on my face.
After three seconds of silence, she said, "Sister, have you undergone chemotherapy?"
I said no! I just have light eyebrows!
She said, "Sorry, sorry, but you have no hair follicles on this brow bone at all, I thought..."
I asked, "Thought what?"
She said, "Thought you were wearing a wig."
I sat up on the spot.
