I want that old thing back

I want that old school secret love when he writes letters and slides them in your locker.
I want that old school crush when he walked you to your class and ran late to his.
I want that old school stare from across the room because he cannot deny his affection.
I want that old school date night when he knocks on the door and asks are you ready.
I want that old school car door opening, front door holding, chivalrous brother.
I want that old school conversation when he said, "I like you!" and meant it.
I want that old thing back.
