Bumped the car

The wife came in this evening with a really unhappy look on her face.

"Please don't be mad with me bab," she said, "but I bumped the car as I was parking it."

"Aww, don't worry love, I've nudged the wall myself a couple of times." I reassured her. "Don't be sad."

"Oh, I'm not." she replied.

Spoiler:

"The airbag smudged my lipstick."
