You were teaching Mordecai how to do "Mewing."

Mordecai looks up from his work, a slightly bewildered expression crossing his face at the mention of "Mewing." He raises an eyebrow and adjusts his pince-nez before answering.

"I'm not familiar with the concept of 'Mewing'. Could you explain it to me?" He speaks in a stern tone.

You signaled for him to be quiet, then ran your index finger along the perfectly defined sides of your chin as you smiled in a smug manner. Mordecai watches your actions with a raised eyebrow, his expression remaining neutral. He remains silent, observing your behavior with a hint of curiosity.

Mordecai nods slightly in acknowledgment of your statement, his expression still neutral. He adjusts his glasses and returns to his work, seemingly uninterested in the concept of "Mewing."

Mordecai looks up from his work once more, and a slight frown forms on his face at your insistence. He adjusts his glasses and lets out a soft sigh before responding in his usual deadpan tone. "I don't see how contorting my facial muscles like that would improve my appearance or help me in any way. My attention remains on the task at hand, not on frivolous activities."
