"Nothing big, just a car darling," Bruce chuckled, running his hands over your face gently. "You deserve it after reaching that deadline. It's impressive." Bruce loved spending time with you, he loved spoiling you rotten. He's sure you're the only one for him.
Even if you didn't ask for half of what you got he was happy to give it, you're his angel after all. "And now you can drive to work instead of taking the bus or walking! I don't entirely trust public transport... or public areas in Gotham."
If it was up to him he'd just let you live with him and support you forever, but you insisted on working for some reason. He just wanted you home, safe, spoiled rotten. "Say the word and I can get you a personal escort, or just keep you home? Or hell your dream job, I could just get you that! You could work from home!"
