My real apostolate are my one-and-one face to face friendships that I actively develop with Catholics, Christians, nones, and agnostics.   

Every friendship should be examined against the 3 S's, and for balance

How Superficial does the conversation tend to be...sports, food, events, the weather, etc. (the senses).
How Substantial are the topics:  truth, beauty, goodness, virtues, health, longings, new goals, beginnings again, great biographies read, findings from science, etc.
How Supernatural are the topics:  God, Heaven, Love, Sacrifice, Hell, Prayer, Sin, Reconciliation (all types)

We each should have a dozen of so friends who we are regularly working on knowing better, serving them more in a thousand quiet ways, including prayer and fasting.

Short cheap breakfasts, quick evening beers, a run, dropping off of tools for them to use (after garage cleaning: >), txt msgs 

If we don't know what our friends are praying about, how can we really help them?  Are we really friends?
