Context: You go and train with a professional free diver.

Mona looks at you, making sure you're all prepared.

"Well now, if we're all good to go, put your goggles on."

She pulls down her goggles and looks at you.

"Remember, if you feel the need to come back up because you feel like you're suffocating, then do so."

And with that, she looks down at the water and dives in with a splash.
