Graphology is the analysis of the physical characteristics and patterns of handwriting claiming to be able to identify the writer, indicating the psychological state at the time of writing, or evaluating personality characteristics (Wikipedia).
I first learned that this was a thing when I saw the film The Talented Mr. Ripley (1999) at age 11. There is a scene in which Matt Damon's character is analyzing Jude Law's character and I've never forgotten it. The loops of your letters, how closely they are next to each other—features like that are said to give insight into who a person is. I'm skeptical (it's largely seen as a pseudoscience), but I also admit that I need to do more research about it to at least be able to back up my doubts. Either way, it's an interesting idea to consider. [note to self: I've noticed that I use the word "interesting" way too often on this blog. I'm sorry.]
I've noticed that my handwriting has changed somewhat, even throughout adulthood. Maybe these changes subconsciously reflect the metamorphoses in my personality. I'm definitely not the same Danielle I once was. This is both a beautiful and terrible thing.
