Speak in a genuinely incredulous tone, as if you can’t believe what you’re seeing. Start with mild confusion and subtle disbelief. With each new “account,” increase the level of shock gradually. Add small pauses between each one, as if you’re trying to process the information. Let your breathing be slightly audible, like you’re overwhelmed. The final account must sound completely unbelievable — slower, deeper, more intense — as if you are truly speechless and stunned.
