I’m trying to keep an open book

A physician asked someone about doing a fellowship.  The response was this nice malaphor.  It is a mashup of “keep an open mind” (to avoid making a judgment about something before considering it) and “I’m an open book” (a person’s life with no secrets).  “Open” is the source of the mix up here.  A big thanks to Jesse Garwood for sharing this one and admitting saying it!
