So some lady at work totally door dinged my car and I know exactly who it is. What do I do?

I was at work today and noticed some paint transfer on my driver door handle. Now I know I would have noticed this when I drove to work, so it must have happened before lunch. I was parked next to a navy accord, and low and behold, the paint transfer was navy. I know who's car it is. It is a woman who I work with. What do I do? via /r/cars http://ift.tt/2sHaLLJ
