1. Remember the Golden Rule
Treat others the way you would like to be treated. Do not treat them above or below you, treat them like an equal.
2. Realise that nobody's perfect
Everybody has quirks and flaws, and accepting each other's flaws is key to a good friendship. Do not judge your friend.
3. Respect each other's opinions
Your friends are allowed to have a different opinion to you, which is what makes us all individuals.
4. Realise that even the best of friends can't be together 24/7
Develop other interests and don't be jealous when your friend has other hobbies or other friends.
5. Communication is really important
Your friend can't read your mind. If something is affecting your friendship, tell them.
6. Be a good listener when she needs to talk
7. Be trustworthy
If a friend tells you a secret, make sure to keep it. Never tell
someone a secret your friend wanted you to keep. Don't even leak it out
to someone you think you can trust. A secret is a secret.
8. Keep your word
If you say you're going to do something, do it. Follow through with it. You know what they say, actions speak louder than words.
9. Don't talk behind your friend's back
Gossip is toxic and can ruin even the best of friendships.
10. Argue with eachother
Best
friends will have disagreements and even argue from time to time. This
is not the end of the world, arguing in a healthy way can actually makes
friendships stronger as you express what you both need to say and it is
an opportunity to learn more about the other person.
