Blogger - Disable "share on google+" (option not found)

Attention Google!  You've gone too far again.  Everytime I update a post or create a new post on Blogger, it offers me an annoying pop up box to share on G+.  I don't want to spam my people (who are so few anyway) everytime I fix a typo.  And I'm sick of this box.  It has no "auto share" leave me alone option and no "I don't want to share" leave me alone option.  I'm stuck searching for it on Google, where I didn't find anything (despite the new annoying social search.), but at least now I'll find this post.
