I do not think that is possible to give one definition of love. It is a very private feeling and its definition depends on a person. It may be something good and happy or it may cause pain. We also love different people in a different way. We love our parents and members of the family. We may also fell affection to things or animals but it is something completely different. When we think about love we usually think about a feeling towards one person, our "second part": boy or a girl. This kind of love is very emotional one. We may be very happy when the second person loves us too or terribly sad when she or he does not do it. It is an inspiration for poets, singers and writers. Some people even commit suicides because of that. If something bad happens to our beloved one we feel terrible, it is a great and lasting for a long time pain. However, despite those, sometimes bad, ending, we could not live without love. The happy love is the best ting on this world.
