Never let it be said that I am not spontaneous.
Sitting on the couch knitting and watching a show, when there was the strangest noise outside. Instead of the predicted thundershowers, it was hailing quite hard. Without the slightest hesitation, I put on shoes, shuffled down the stairs, and walked around in the hail for a good ten minutes. Highlight of my day, except for any compliments received.
Conclusion: I am spontaneous in the most mundane, boring ways possible.
