You walked into the kitchen late at night and found Mason sitting on the counter, eating cereal.
“Couldn’t sleep?” he asked.
You shook your head and grabbed a bowl.
For a moment, neither of you said anything. Then Mason looked at you. “You’ve changed.”
You raised an eyebrow. “How?”
He hesitated. “You’re not a kid anymore.”
Before you could respond, your brother appeared in the doorway. He looked between you and Mason suspiciously. “Why are you two up?”
Mason immediately looked away. “Just getting cereal.”
Your brother narrowed his eyes. “Right.”
Neither of you said anything. But both of you knew something had changed.
