Answer:
I'm gonna do each one, with an example, and maybe you can take inspiration from one of them.
- Treat others as you would like to be treated
People bully others all the time, yet they freak out if someone fights back.
In my experience if you treat the bullies like they are treating you (such as calling them names) they usually freak out, and tell everyone how much a bully you are, even though they are doing the same thing to you. However, if you treat them nicely, and don't stoop to their level, they tend to move on from you.
- Don't take material that doesn't belong to you
At school, work, home, and even just on the street people get robbed. Person A takes Person B's pencil, or CoWorker A takes CoWorker Bs project idea and presents it as their own.
- Don't feed the trolls
People online feed the trolls all the time, arguing back or bringing outside attention to it.
- Don't believe everything you see online
Especially right now, people need to look deeper into if something is real or not. It's like when people don't take an Onion article with a grain of salt, (If you don't know what The Onion is, it's a Troll sorta "News" site. Which feeds back into "Don't feed the Trolls"), and instead they get angry about it.
- Think carefully on what you post online
People think that just because their words are said online and not in person, they don't hurt. There was a case where someone's sorority sisters posted pictures of them online and made nasty comments on how she looked, and that girl eventually developed an eating disorder.
- Be careful with Info
There are multiple cases where children give out their address to online "friends", or their phone number, which is really dangerous not only to them, but to their family.
I hope this helps!
