Paul Butler needs a dictionary. (or what do you think the word 'solo means?)

Howdy!

Last I heard, the word solo meant 'alone,' 'by one's self,' 'without others.'

Last I heard, the word party meant 'a group of people gathered together for pleasure.'

So why does Paul Butler have his collage parties listed in the Solo Exhibitions and Installations part of his CV? Does this mean that the other people are superfluous? or is it that Mr. Butler is taking credit for their work? Or is that he doesn't expect anyone reading his CV to go beyond the Solo Exhibition section and he figured he needed to get it in at the beginning? Or is it something else?
