A Bongard to Make Your Morning

Curved lines transect shapes, and straight lines touch vertices of the shapes [assuming the vertice is composed of 2 straight lines and not a curved line]

Left: all straight line segments are connected with no breaks, and all curved shapes have tangent curves that 'hug' them. Right: some straight line segments have breaks, no tangent curves to the curved shape boundary at all.

You can draw an infinitely extending straight line that enters and exists a grey area for the figures on the right but not the left which always gets obstructed by a black line

Straight line can't enter and exit the grey area without touching a black line vs straight line can enter and exit grey area without touching a black line
