Apple eating

I watched a girl eat an apple in the library today. It was one of the most curious things. She held the apple with both hands and ate it like a piece of corn. (She went around, not side to side.) Then, after each bite, she would chew for about 30 seconds. (I didn't realize a bite of apple had that much substance to chew for 30 seconds.)

I don't have enough patience to chew a bite of food (let alone an apple) for 30 seconds.
