Stupid comment. It’s because he’s left handed and his hand moves over what he just wrote. Send this link to Steve Hilton:
Pentel EnerGel RTX RT Liquid Gel Pen "Pentel EnerGel gel pens are highly recommended for left-handed writers due to their exceptionally fast-drying, low-viscosity ink that prevents smudging. The ink dries almost instantly, reducing the common 'lefty smear' while providing a smooth, skip-free writing experience."
