He recognizes this pattern. The one where you’re never available and abnormally irritable, almost completely ignoring him for days on end.
You’ve always been more dedicated to school than him, all high A’s and AP classes. Not to mention you’re involved in so many sports and organizations that he can hardly remember them all. You’re good at everything you do, but he knows the cost of that talent.
That’s why he snuck out to walk over to your house tonight. He could tell from the look in your eye in class today, even the difference in your handwriting, that you aren’t sleeping. Typical of you, but he can tell when you’re close to breaking down.
He finds the spare key under the same speckled rock, knowing your parent works nights. Letting himself in and locking the door behind him.
