What quality do you value most in a friend?

Friends are like flowers in a late Spring flowerbed. They are all unique and are perfect in their own ways and in their own time. Some are fleeting and others are perennial. I would find it hard to pick out a single quality that they have in common, but as an ensemble they are a fabulous bunch. Friendships, like these flowers all change over time but as long as we can all still get along does that even matter?
