Place it right after the food is offered and before the other person's reaction, so the refusal becomes the turn in the scene. Follow it with You What for a confused reply, then close with DJ Airhorn when the argument over the plate escalates.
About this sound
This short French voice clip delivers the line 'I don't eat seeds' in a flat, matter-of-fact tone, lasting just over three seconds. It lands as a dry, stubborn refusal, funny because it sounds so final about such a small thing. The blunt delivery makes it feel like a deadpan no to anything offered, turning a simple food preference into a comic stand-off.
