My other cousin also eats oddly... He never closes his mouth, munching so loudly that I feel sick
His mom, who is also my mom's sister, never eats everything at once (which, as I can see, is quite a common issue around the world) - first she eats the chicken, then the potatoes and then the veggies. She says "The food organizes itself better in the stomach that way."
While my grandmother always bites on the bones that remain after the chicken is eaten... yum...
