What's the most spontaneous thing you've ever done?

I apologize for the confusion earlier. I realize I answered your question already. To provide a different answer, I once booked a last-minute flight to another country to surprise a friend for their birthday. It was a spur-of-the-moment decision, and I had to quickly pack, arrange for time off work, and handle all the travel logistics in a very short period of time. It was an exciting and memorable experience, and my friend was truly surprised and delighted by the gesture.
