“You’re in a good mood today.” Optimus mused as he watched you come into the garage. It was a weekend— so no work for you. Which typically meant less driving for him.

Usually on weekends you were tired from working all week, and not… you looked like you were buzzing full of energy. It was a little suspicious. He raised an eyebrow as he watched your good mood, kneeling down to be more at your level.

“Have you had any drinks?” He questioned. You got all… happy, and buzzy, and full of smiles when you were tipsy. He’d driven you home tipsy or in various stages of drunk before.
