Druid wisdom...

A Druid Triad:

The three foundations of friendship are: respect and trust; understanding and forbearance; a loving heart and helpful hands.

For friendship to last and for it to be deep, it is not enough to simply like each other. There must be mutual understanding and tolerance, trust and respect, and above all, there must be a genuine fondness for each other, and a willingness to be of help, when needed.
