Sweet pig feet in the teacher's break room

I walked into the teacher's room during break time today. There are usually beverages, communal snacks and rice cakes to share. One of the male teachers picked up a plate of pig feet and offered me some with a smile. Excuse me? I glanced at the clock, it was 10:32am. It only took me a second to recover. I smiled and took a piece. It was sweetened and we dipped it in soy sauce.  It was my first time eating that part of the pig. I am, however, familiar with some of his other body parts. I was able to eat everything but the knuckles and toenails. 

LOL, don't judge me, after all, I am in Rome.
