I totally get this happening at a retreat where everyone is working on their own projects at their own pace. We have a retreat attendee do this and it's annoying. Since there is much chatter and helping going on with everyone, her's stands out cause she generally has no idea how to get started on the project she brought and wants someone to get her going on it instead of just giving an opinion or helping to problem-solve. Some don't mind this, but most are trying to catch up on projects that have been sitting for awhile. And that is what we've started to let her know-that we are trying to play catch-up on our projects and feeling "crunch time". She decided not to come to retreat this past time.
