SH+trust

http://dictionary.reference.com/browse/trust

Trust is a very important factor of friendship because it allows one to depend on the other, knowing that they'll always be there for you no matter what. In a friendship trust is very important and has to be earned because it's a very valuable thing. The line, "The friendship must be based on trust but, like the flower, it's started with God's love" proves that this is true.
