In these two images taken a few seconds apart and from different angles, Angela Merkel speaks on her mobile - and tells us more than she believes.
This configuration a reliable nonverbal indicator that she feels in need of distancing herself from the person and/or the subject manner with whom/what she is speaking. In addition her fingers are splayed slightly more apart than is her (or most others') normal baseline when holding a phone. She feels that the person or subject matter is in some way "dirty" and she wants to minimize contact with it/them.
A useful and parallel body language metaphor is brought to mind when visualizing picking up a soiled rag - we extend some our fingers apart from it, lessening our contact with what is undesirable.
