Collaborative Art

Here is what happens when I leave a spiral notebook and a black Sharpie on the bathroom hamper. It started when I mindlessly doodled a few random lines. My daughter would come home from college and add a few more lines. She came and went, graduated. I graduated. We kept adding lines.

Is there a message in this collaborative work? I don't think so.Except maybe that the apple hasn't fallen too far from the twisted tree.
