" She slapped my arm surprisingly hard. 'Not with words, with whispers.'
'But you said-'
'I said, you said... Stop saying! The spirits, they don't like loud things. That's why they come out here where it's quiet, where no people are. They don't need you talking at them, just whisper!'
If it had been as simple as just whispering the words, that would have been easy. But it wasn't, as i discovered when she smacked me again. "That's just talking quiet. "
