O uso do DOES
That's a matter of interpretation.
"I know, we have talked about this a lot..
But does not the idea of leaving appeal to you?"
"We have talked about it
But does not that
appeal to you?"
Quando usamos 'his, that, the idea of'
ou qualquer substantivo, pronome, enfim a idéia de terceira pessoa do singular, e pudermos entender como ele, ela, aquilo, aquele, aquela, etc. DOES
é o auxiliar correto. Se a idéia for de plural use o DO
