In most instances, it’s a waste of words (and boring as hell) to have a character reply with “yes” or “no.” Instead, have them explain their reaction.
Example:
“Did you have a good evening with Bill?”
“Yes.”
“Did you have a good evening with Bill?”
“It was spectacular. He took me to the top of the Hancock and we watched the sun set. Then we went to the restaurant for dinner. And then…”
“Okay. I don’t need to know any more.”
Of course, if the character is, for example, a recalcitrant teenager, a monosyllabic response would be fine.
