Why do mashed potatoes not reheat well?

Mashed potatoes reheat poorly because their cooked starch molecules absorb liquid and swell; when cooled and reheated, especially too quickly or at high heat, this leads to starch retrogradation, causing dryness, glueyness, or a grainy texture, while water in frozen potatoes forms ice crystals that separate, making them watery.
