Holding up a mirror

Yet again I love the serendipity of chasing ideas and, as my friend describes it, joining the dots.  

• In the back of my mind the metaphor of coaching as being like holding up a mirror to someone. 
• earlier in the week a link to Bruce Britten's blog on Organisational Learning and paper engineering and the two quadrants of the model like the JoHari window 'We know what we don't know' and 'We don't know what we don't know'
• and today coming across the brilliant cartoon from Delta 7 on personal blindness.
