This is probably somewhat illegal but what the hell. Anyway, have you ever talked to someone who repeats how happy/smart/humble they are? When that happens, I always wonder if they're saying it to convince me, or themselves and then of course, my imagination conjures all sorts of lurid possibilities as to why. Unlike most four year-olds, a writer never grows out of the "why's".
This scene from Breakfast at Tiffany's is pitch perfect in conveying subtext. It helps if you've seen the film in its entirety to appreciate Holly's subterfuge, but Audrey Hepburn's performance does a lot of the work for you.
Check it out and then have yourself a great weekend!
