Understood

A friend referred me to a young lady concerning some work I needed done. I met with her and she appeared qualified, ruling out her kelly green hair as irrelevant.

I said I'd like it done as quickly as possible. Would tomorrow be okay?

"Yes. Oh wait, no. I'm having my hair done. The roots are beginning to show. You've probably been around enough women to know I have to take care of that."

Of course. You wouldn't want anyone to know that green isn't your natural color.
