People who study and interpret handwriting are called graphologists. Some people believe that the way you write tells others more about you than what you tell them. They believe that:
Bold, thick letters suggest that you are active, average size letters suggest that you are well balanced and light, thin letters suggest that you are sensitive.
If your capital letters are large, it means that you are a proud person; if they are small, it may mean that you are modest.
Small spaces between words may mean that you are someone who does not like change.
Handwriting that is easy to understand indicates that a person is a good communicator.
For fun, why not analyze a sample of your handwritings and see what you will discover.
