Suppose a situation in which you are filled with joy and excitement. Something good has happened in your life. Your child just had a big promotion. Your grandchild scored a winning goal. You just returned from the trip of a lifetime. You want to share your joy with somebody, anybody, everybody. So whenever anyone shows an interest, asks "How's the family?" "Was that your grandson's picture I saw in the paper?" "How was your trip?" you are ready - perhaps with pictures.
When does sharing your joy become bragging?
