You've started your story, introduced us to your main character, and things are going well, but if you don't introduce us to that sexy love interest soon, people will yawn - what better way than a collision course?
Crash Into Hello - a quick, usually action oriented way to introduce two (or more) characters to each other, often because a character is running late and is not paying attention to where they're going (with multiple variations). This trope can be used both for comedic or dramatic effect. < in this case, Catch Into Hello.
Remember when Bella met Edward? Yeah. Potential boyfriends don't usually throw themselves into a car's path to save a girl. Well, maybe they do, but the boy rarely gets out of such a clinch without a scratch.
Crap ... I nicked a nail!
When Korben met Leeloo, he never thought the girl of his dreams would crash through the roof of his cab.
Future girls don't use doors!
Sometimes the Crash happens by other means and requires a rescue - Hello still finds a way in there.
Sometimes it's good to miss the train ...
These encounters are typically messy - papers fly, books drop, or orange juice spills all over the place.
Other examples of this trope include Sturm and Alhana from The Dragonlance Chronicles, the last minutes of The Secret of NIMH, and a scene from season 2 of Heroes, including countless examples from Anime.
Since people typically watch where they're going, this trope is not always easy to pull off effectively - but accidents do happen, as do chance encounters. Feel free to take a creative approach and crash into it!
Ever used Crash Into Hello? Has this happened to you in real life? Name other examples? Do you have $3.50?
