THE GOLDEN RULE:
TREAT OTHERS THE WAY YOU WANT TO BE TREATED
The golden rule, we've been hearing it since first grade. There's a very important reason we've been hearing it for so long. The golden rule is "Treat others the way you want to be treated." which doesn't apply to everything, but it does in a lot of things. Has someone been rude and made you really mad and you yelled at them? That applies to the golden rule. Have you ever complimented someone and they were really nice to you for some time after that? That applies to the golden rule.
The purpose of this rule is for others to not treat others rudely because, ideally, you wouldn't want someone to be rude to you, and someone being rude back serves as a consequence for being rude to them in the first place. Then if you're nice to someone, you'd ideally want someone to be nice and friendly to you.
For some people, they don't apply to this rule. They may simply not care if someone's nice to them, or if someone is mean back. In fact, they like to see someone disappointed because they were so nice, or laugh at someone trying to be rude back. The rule is still very important, because in the face of kindness and respect it serves a big purpose even though rude people may simply not care.
It's so important because it teaches others to be nice, it teaches others to think before they speak, and it teaches others that if they aren't nice to someone they won't like the outcome. Some people still don't have the courage to let out all their anger, but some people are just shy around people and that's perfectly okay. If you want to let everyone know how you feel, that's perfectly okay too. I know everyone hears this a lot, but everyone's different and nobody's perfect, and as common as that saying may be it isn't any less true. And as common as the golden rule may be it isn't any less true.
We've been hearing it for so long because it's true and it plays a big part in regards of respect and kindness.
is this long enough? i'm not sure. anyways, hope this helps :)
