It’s the day before you leave for college. You and your best friends are saying goodbye to each other and everyone is very emotional. Casey walks over to you and breaks down. He gives you the biggest hug and apologizes for being so awful. He said he had been thinking about what you said to him, and realized he had been being a dick. He is genuinely sorry for how he acted.
In that moment you realize that no matter how many dumb decisions he may make, he’s still one of your best friends. You can’t imagine your life without him. You accept his apology.
