Without the details of the story, it's just guesswork. One main event could be that they discovered a secret place while exploring their town. And then, they might have had a big argument but later resolved it, which could be another significant event in the story, strengthening their friendship in the process.
One main event was his victory over Goliath. It made him famous. Also, his becoming king is important.
Well, in King David's story, his relationship with Bathsheba is quite a significant event. His lust for her led him to commit adultery and then try to cover it up by having her husband Uriah killed in battle. This was a great sin. Also, his early days as a fugitive from Saul are important. Saul was jealous of David's popularity and tried to kill him, so David had to flee and form his own group of followers, which later helped him in his rise to power.
Since I don't have the full 'David's new friends story', I can only speculate. Maybe David's new friends were from different backgrounds. This led to some cultural exchanges among them. For example, if one of his new friends was from another country, they could have shared their traditional foods and stories. They might also have formed a club or a team together, which strengthened their friendship. And as they spent more time together, they became really close and had a lot of fun memories.
The main events in King David's life include his anointing as king by Samuel. His victory over Goliath was crucial as it brought him to the public eye. His ascension to the throne and his reign, during which he made Jerusalem important.

At the end of King David's story, he was old and frail. One of the significant events was his son Absalom's rebellion against him. David had to flee Jerusalem. Eventually, Absalom was killed. Another aspect was David's choice of Solomon as his successor, which was an important decision for the future of the kingdom.
