Have you ever been betrayed by your best friend? Do you think your best friend is a real friend or a fake? Here are some ways you can tell...

[edit] Steps

Ask them if they can go with you on errands. If he/she says yes but afterwards refuses, you know that one's a goner.
Ask them if they could stay with you after school. If they say yes, but then say he/she has other plans, you know they probably doesn't want to be with you.
Call him/her to talk at night; if they talks for a while, then says he/she has to go without a reasonable explanation (or makes up a "reasonable explanation" every time), their probably not a true friend.
Watch if you're always the one starting conversations. If your "friend" doesn't email or call you like they used to, they're probably not your best friend anymore.

[edit] Tips

Avoid people who change after one year of school.
Avoid people who try to be something that they aren't.
Avoid the people that hurt you.
Just stay with the friends that know all your secrets and that are loyal to you. It doesn't matter if you have just one best friend because at the end you will be happy with that one friend.

Watch out for people who become your friend only after you become popular.
Watch out for your friends who approach you when they need something from you. Don't let them use you.
Make sure your best friends love you for who you are and not for your reputation, wealth, or your relationship connections.
If he/she gets into a relationship it might change things but still wont change how good or how much he/she feels about you, its just they need there own space from time to time
