Joyce Myers has a great way of putting things into perspective (very cut and dry and true). Yes, I suppose putting faith into another person is rather foolish and I never really thought of it along those lines. It really sets us up for disappointment whether the person is an A or not. Lord knows we've all been disappointed many many times. People are after all- only human.
I've stopped expecting things from my AH too. It's no longer worth the energy that I once put into it. Whatever comes my way each day I am doing my best to put into perspective as it comes.
