Is the following text has a mistake or is it correct?
This book say "say" about 3rd person singular, apparently instead of "says", but I'm not sure if it is a typo or it's acceptable in such kind of literature (it is a professional book) or maybe I miss here a grammar rule.
This is a phrase from a book so called "Discovering Fiction Level 1 Student's Book":
One day he overheard her talking about him with a friend. Lucile was saying:
"other men live in things and events and emotions and the future. but he seems to know that living is something else..."
What else? This friend interrupted curiously.
and he heard Laucile say: "Well, of course every one knows, really. But he lives it too.".
