<u>Explanation:</u>

However, in time his boasting attitude changed to a true pride in his heritage. Making his friends believe that his great-grandfather is like the Indians seen in movies.
In time his friends visited his grandpa and are impressed with his great-grandfather, however, Martin is ashamed of himself, but later begins to feel that his Grandpa is a great man.
Next, his great grandfather teaches Martin the value of the medicine bag and how the bag teaches very important life lessons which included the popular saying that things always happen for a reason.
