How do we say "Goodbye?"

How do we say goodbye to friends?  Hopefully, it won't be goodbye, just a farewell or see you later, until we meet again.  It is always hard when one thing ends and another begins.  Sometimes you are ready to move on and other times you wish you didn't have to go.  I suppose everything must come to an end, and all we can do is hope that the journey was fun and that we learned a lot along the way.  Friendships were formed, and I hope that they last a long, long time and stay true.  As for what is to come, I am an eternal optimist, so I am looking forward to the adventure as, I hope, are you.  Have a great summer!
