MOST impulsive is probably not a topic for CC.
I'll go with most recent. ..my sister was annoying me on the subway, and i didn't want to get in a fight with her in front of her very sweet roommate, so as soon as the subway doors opened I hopped out at some random stop and told them I'd meet them at their apartment. Granted, it was past midnight, the trains were infrequent, not too familiar with the area, and my flight home was that same morning, so I really had not thought this through.
They followed me out before the doors closed and we ubered home, and my sister and I were 100% all right again
