There are many things you can do to keep friendship strong forever. Trust is very important in keeping any relationship strong and long lasting. If you trust the person whom you have a good relationship with and the other person also trust you in the same way, then you two have a good relationship. You can remember important date of your friends such as their birthdays and wish them or give gifts to them on the special days. Many people say that money is the most important thing to consider, but remember friendship is not about money. You can find something small and inexpensive for their gifts or send online cards. A friend should also always help others even when it is not very convenient. So have a helping hand ready at all times. Sometimes distance makes relationships even closer. So, if you are far from your friends, there are many ways you can remain in contact（联系）. You can use email, chat programs, and you can also write a blog and share your daily life activities with your friends. If there is anything that makes you happy, share it with your friends. Listen to their thoughts as well. If they have achieved something noticeable, congratulate them and celebrate with them. I have seen good friendships and when there is unhealthy competition between two friends. Though this may not happen in many cases, it is better to keep this idea in mind since it may happen to you. As far as I have seen and experienced, it will be better not to either lend to or borrow money from your good friend. Of course, we have to do this with friends. But, attention should be paid so that your friendship may not end. How to Keep Your Friendship小题1:______
