I will just say that arts and crafts are wonderful enjoyment. Many people can derive hours of peace and contentment using simple paper and pencil, or perhaps even a sketch journal and oil pastels.Many make their living with a drawing lead and paper, such as architects. The lady in this video must fall into the latter category, as it appears she is attempting to use a straight edge for some lines.
The crafty four legged visitor has other ideas. He uses the stealth of the paper curve to hide and attack when his drawing human leasts expects it....or maybe she does expect it and gets way more enjoyment from watching the cat than actually drawing!
