What movie is this?

It's an old movie. Black and white and the main characters are 30 and 22 years old. The 22 years old is a female and asks a ton of questions and is very open. All her lines may be questions. She acts very innocent and disregards the 30's moves on her. She somehow ends up at his house sewing a button on his coat, then deciding to make dinner at his house and that's all i saw of the movie.
