Do you ever think about something and then a mildly related topic pops into your mind? Then from there it branches out into something else somewhat relevant to the original thought? It's a web of ideas all building and branching off of one another. At first, it's all closely related in the brain storming. But then you keep branching out until it seems really random. But only you truly understand how bananas are relevant to Joe Biden's campaign 30 minutes after staring at a wall, wild eyed, thinking about it. It's all related!
