True friends double your happiness and half your burdens.Basically how you would like a true friend to be is what you should be like to your true friends.Trust,forgiveness,

responsibility are some elements of a true friendship.True friendships are hard to achieve.

And what’s more,life is short.So treasure these friends if you already have them.If you don’t,

continue to search,because once you have them,life will become so much easier to live,no matter what happens.I have been through very difficult times and I dare say,without my friends,

I would not have made it.

Friendships need lots of energy and patience to maintain them.Not to mention time.When your friend needs you,and when things are not going too well on your side,it is often so easy to  turn a deaf ear to  their requests.It is especially during these times that you must find the strength to help your friend.

And it is during these times that your friendship will be made stronger.

And you must always be happy for their successes,even when things are not going too well for you.It might be hard to do this,but it is something that you need to learn.Think about all the sacrifices your friend has made for you and all the times when he was happy for you despite his own troubles.Think  aboutall the happy times you enjoyed and the sad,difficult times you went through together.That should give you plenty of patience to actually be a true friend.Remember,true friends are the next best thing to family.They will always be your supporters.小题1: What is the best title for this passage?
