    It is difficult to find true friends these days. A lot of people would backstab(背后伤人). Some make friends just to use them. Others promise to be your friends but they are never there when you need them the most. They appear only when they need something from you.

    Once you find a friend who is worth keeping, make sure to take care of what you have with that person. How? Here are some tips on how to make friendship last forever:

    1).Call for no reason. Call just to say “Hi” or just to ask “What's up?” You don't need a huge or an important reason to call a friend. If you can't call, just send an e-mail. This would send a message that you remember your friends at any time of the day.

    2).Know when to say I'm sorry and thank you. Don't let pride get in the way, especially when you are wrong. The word “sorry” already has saved a lot of friendships. Show praise for the things, big or little, which your friend does for you. Did she listen to you when you were complaining about that physics exam? Did he offer his shoulders for you to cry on when somebody broke your heart? Say thank you. It's that easy.

    3).Avoid hurtful words. If you have nothing good to say, don't talk at all. Don't hurt your friend's feelings by saying hurtful words that, most of the time, you don't really mean. If you're a true friend, you will be careful with your words.

    4).Don't lie to a friend. Trust is the first thing for building up true friendship. Write them a note from time to time. Also, try to be thoughtful. Give simple gifts that will make their day.

    5).Know how to keep a secret. Show your friends that they can depend on you to be there whatever happens. If you promise to keep the secrets for your friends, just do it.

    6).Be generous with your time. Spare some time to see your friends however busy you are. You can always spare an hour or two after school or work to visit them.

    If you are the type of person who knows how to take care of friendship, you are certainly a keeper!
