Hi,
I have made/read a comment on G+ with a photo of our well known 'service crew'...
I 'accidently' moved the pointer over the faces of them and the browser just popped up a circle with the message
"click to tag this face"....
I laughed a little bit as I saw this.... and laughed a lot more as I saw that this doesn't work for Eric....

I always thought that he doesn't look really natural and human
