a lot of friends are a waste of time

to begin with i`d like to say that friendship is the most important thing in the world. it is no doubt, that everybody should communicate, have chat and spend time with each other. but to my mind when you have a lot of friends, you will waste your time useless. for me, leisure is the time for rest and relaxation, and when there are many people around me i can`t amuse because they can disturb me. you even may feel lonely thought many people are beside. i prefer to have a friend who really can help me or simply listen to me. the same happens when i work or study. i think it is better to give all your free time to your favorite occupation. it's all according what you want to do, but to have a lot of friends is difficult because you need to devote considerable time to them.
