S, you know how I feel about you, so I want whats best for you. You really should stop getting so involved with h about things. It is not your responsibility to tell him about the C sessions and calling him to ask if he wants to change it, take a differnt slot, or whatever. He has the schedule or if he isnt sure, he could call the C or you. .
You need to only call him if something important is going on with S17 or the finances. You have to give him some space.
