Frustrated

"I don't smell anything at all, Sis!" Ayumi replied, her voice shaking from being flustered .

"Why is your face so red then? And why are you sweating so much?" her sister questioned, clearly picking up on Ayumi's unease. 

"It's, um, nothing. It's just because it's hot!"Ayumi stammered. She tried to play it off, but her embarrassment was too obvious .

'Please try not to be too obvious. I can practically smell your lie from here,' I whispered to myself, unable to hide my worry as I facepalmed myself.

This girl was so honest that her face couldn't even keep up with a lie, even if it meant saving her own life. 

"Nonsense, the air conditioning unit is on, and it's not even hot right now. Are you hiding something from me?" she insisted, determined to uncover the truth.
