Don't be dismayed at goodbyes. A farewell is necessary before you can meet again. And meeting again, after moments or lifetime, is certain for those who are friends.
Why can't we get all the people together in the world that we really like and then just stay together? I guess that wouldn't work. Someone would leave. Someone always leaves. Then we would have to say good-bye. I hate good-byes. I know what I need. I need more hellos.
