I once travelled to another city to go to a Purity Ring concert. After a one and a half hour train journey, the minute I set foot on the station, I realised I forgot the tickets at home. That was back when physical tickets were a thing. Thankfully I planned to arrive early to do some sight seeing before the gig. That gave me just enough time to take the train back, get the tickets, and take the train there again. It was worth it!
