My colleague, site manager.

We have a site guide on the radio, who undertook to maintain our site, but put it on it and crawls for days in contact, sitting in ICQ. Constantly trying to tell something when no one is listening. His stories are “nothing” and abound with a billion unnecessary clarifications. For example, "we walked across the field, there the grass was at first high, and then low, and then generally the field, one scene was on the left, the other was a bit off." Even when you don’t listen to him, he continues the story anyway, and now, he is sitting opposite me, seeing that I am writing something, but cannot shut up.

And the site is still closed. By the way, I let him read it .
He agreed that about him and continued to crawl on contact.

how to deal with such phenomena?
