    Often, people who need technical help have a high-level goal 
    in mind and get stuck on what they think is one particular 
    path towards the goal. They come for help with the step, 
    but don't realize that the path is wrong. 
    It can take substantial effort to get past this.

Because the room lights could be turned off to not shine on the 
wall, it was easy to see.

Someone kept asking how to write SQL when using an ORM,
so a presentation on the benefits of using an ORM is needed.

        with --no-site-packages?
