WWYD?

If you're stopped at a light and some guy in the lane next to you jumps out of his car and walks over to you and unexpectedly slams the hood of your car shut and then gets back into his car and drives off, do you try to catch up so you can thank him or do you laugh thinking about how odd the whole scene must seem to everyone else on the road, when you know that guy was actually your husband shutting your hood  after you had to jump start his Jeep?
