While reflecting on drama, let me just say, that most of you are good people. And you shouldn't let life or the people in it make you unhappy.
When old friends leave, wish them well on their travels.
Do not miss them, remember them fondly.
When new friends arrive, welcome them kindly.
There are a lot of people to meet out there and they're infinitely interesting. The world is filled with them! Make the most of knowing them.
