What are the unifying similarities of incidents relating to Odysseus' pride?

        In The Odyssey, there are a few similarities in incidences relating to Odysseus'

pride.  When Odysseus escapes from the Cyclops, it is his pride that causes him to yell

out "If anyone asks you who poked blinded you, tell them it was Odysseus."  As a result

of this one prideful action, the Cyclops tells his father Poseidon, god of the sea, what

Odysseus had done.  As a result, Poseidon would not allow the seas to carry Odysseus

home for 10 years.  Another incident involving Odysseus' pride occurs when he is in

Phaecia and he is challenged to a discus-throwing contest.  He is mocked by his

challenger, Euryalus, to the point where he feels that he must take up this challenge to

preserve his precious pride.  Though he wins the contest, all who witnessed it become

very intrigued and they ask him who he is, forcing him to reveal his identity, which he did

not want to do. 

         Both of these examples of incidents relating to Odysseus' pride show us that pride is

one of Odysseus' weaknesses.  As seen in these examples, every time Odysseus yields to

his pride, something bad happens as a result.
