Do you think Adam learned a valuable lesson from the events on the bridge? Why or why not?

Adam is a teenage boy who appears tough by smoking cigarettes, wearing a black leather jacket, and bragging about engaging in fights and making out with girls. While Seth is impressed by Adam's bravado, Adam reveals his cowardice at the end of the story and lies to Seth about why he couldn't intervene in the fight, making it clear to Seth that Adam is a compulsive liar. I think Adam learned that being caught in a lie destroys he credibility.
