1. Be your own best friend first.
Learn how to respect yourself. Decide what boundaries are important to you and respect them. Understand what values are important to you, stick by them and seek others who honor those values.
2. Be loyal.
Stick up for your friend when they need it. Respect those times when they need to stick up for themselves. Trust your friend and allow yourself to be vulnerable with them. Also come to understand their limits and say "no" when you need to while still being their friend.
Nobody likes a best friend who just talks and talks, but never listens. If you're a chatterbox, it's okay if you're also a good listener. Whenever your best friend says something, listen carefully and say something. Don't just say "yeah" and move on. Don't interrupt or fidget continually while they're talking to you. If they ask for advice, listen carefully and give them the best advice you can. It'll earn you respect and of course, make them come to you more.
4. Be trustworthy.
If they tell you a secret, keep it, never ever, ever, tell someone a secret your friend wanted you to keep. Don't even leak it out to someone you know you can trust. A secret is a secret. Don't gossip about your best friend, don't say anything that might turn into a rumor, and don't do things that you know would upset them. For example, if she/he had a crush on a cute guy/girl she/he would be embarrassed if you told someone. Make sure you know your best friend is okay with it. Things like that are sometimes hard to do, but if you want a solid friendship you have to be trustworthy.
5. Spend time together.
Hang out on the weekends or plan activities together every now and then, do some homework together, and chat during break at school. You don't have to live in each others' pockets, but make sure you spend some quality time together with your best friend to make the friendship grow and become stronger.
6. Care for your best friend.
If they're away from home, send them cards or care packages to show that you care. If they're sick, call them and ask how they are doing. Best friends care for each other. Show them you appreciate their presence in your life. Write them notes to show that you care and are thankful for them, and ask about their lives. Share your own stories, but make sure you have time for them.
7. Avoid Expectations.
If you assume what best friends' roles are, you will get disappointed and frustrated. Best friends are one of the most valuable friends you have, but they cannot help or support you in every aspect of your life. Do not expect them to always be there, or expect them to say the thing you want to hear. If there are expectations your Best friends need to reach, that will only leave you in a disappointing defeat. Be nice, do not email them saying they are a liar or you won't feel so good.
8. Share laughs.
There is nothing like laughing and smiling to bring people together. Besides, when they're really friends, you guys can laugh at the dumbest and funniest stuff.
9. Be yourself.
You are who you are, and your best friend will accept that. Being "fake" could lead you to losing your best friend.
10. Spend some time together.
If you feel like you are drifting apart a little then maybe think about doing something together one day, like going shopping or having a sleepover.. you know something fun. Most girls would know that being a best friend means telling gossip that you have heard and you need to fill them in on it. Sometimes you might think it's hard but it will get easier, you just have to know what your doing.
11. Maybe you weren't meant to be best friends.
If neither of you make an effort to get together, or if you get into fights with them for no reason, then maybe you weren't meant to be best friends. It's natural to stop having chemistry with a certain person, and if you grow apart, just be happy for the good times, and know how lucky you were to have that great person have a part in your life.
12. Never leave them.
I've done this many times before and I regret it alot. Never say "Yeah, I'll walk home with you!" or "I'll meet up with you tomorrow" and then you don't do it. That makes your friend think do I really trust her? Never do this.
13. If they pick another friend over you, just try to be friends with her friend too.
Maybe you guys can be a group of friends! Everyone is always looking for new friends!
14. Remember, a friend is a gift for you.
You should stick up for them when they have problems. You need to ask them what problems they have. You can't just blabber away and say stuff about them because they never told you anything.
p/s: as the time passes, friends come and go.how i miss him!!
