I was prepping Rama before we saw Stardust. In the movie, a fallen star (Claire Danes) is on the run from an evil witch who wants to eat her heart out - literally. So we were talking about the physical heart.
Me: Close your fist, Rama. Ganyan kalaki ang heart mo sa loob. Tapos, may mga butas yan.
I proceed to hold my fist up, make quick pumping movements and, add my sound effects, puh-pum, puh-pum, puh-pum.
Me: Alam mo ba kung bakit ganyan ang sound?
Rama: Kasi umuutot siya?
