Hello there! Here are some ways a writer can describe about two characters to help develop their personalities:
Through their thoughts and actions:<em> How they react to or what they think after certain situations can show if they're sympathetic, jealous, rude, stuff like that, basically their traits.</em>
Hobbies/Interests: <em>What they do for fun can tell a lot about them. For example, a serial killer and ballerina are, well, very different. Showing what they do reveals them more as a person.</em>
How they present themselves:<em> this can show a lot about a person, especially with how they take care of themselves, if they shower often, how they walk...</em>
How they interact with other characters: <em>You know the cliche grumpy old neighbor - or the snobby popular girl? These cliches are built up from how these characters interact with others. A snobby girl could talk down on people she believes are not as good as her. the grumpy man may yell at kids for crossing his lawn</em>
These are all factors you can take into account. In summary, how characters interact with their environment, society and themselves really goes to show their personalities. I hope my answer was helpful, have a great day!
Wind, water, tide and muscle - both animal and human - provided sources of energy that are still available to man and are still used to power simple machines in many parts of the world today.
