Friendship is a constant throughout the galaxy. Once a friend has been made, it is always remembered. But a friend is not just someone that adds his name to a list. He is the man you can call at three in the morning to pick you up from the airport because your expected ride evaporated, and you need to get home to see your dying mother. She is the one that will support you and encourage you even though she has a blinding headache and the in-laws are coming that very afternoon. Everything of value costs something. Friendship only costs you some compassion.
