What’s the sound of your heartbeat?

During Sofia’s recent check up:

Pedia: I will just listen to your heart okay?

iya nods…

Pedia: Want to hear the sound of your heartbeat?

iya tries on the stethoscope…smiles…

Pedia: can you hear your heartbeat now? It says lub dub… (this is the medical term they use i think)

Iya: (protesting) NO!!!! my heart says dugdugdugdug! (as in hinukay! lol!)
