I had let my younger brother go to a party with alcohol. He passed out and didn't answer his phone, then an ambulance went to the house. I felt a deep sinking feeling and a lot of concern, worry, terror for my brother's wellbeing. I had no vehicle at that moment, it was past midnight so no buses were running and I couldn't even get a taxi without a long wait so I ran there. It was a few miles and largely uphill, but the run didn't bother me. I arrived at the party only to find out that the ambulance was for another kid that had been there, the relief was substantial. The kid recovered fine.
