Train trouble

Yesterday's evening, I went climbing with my best friend, but we took a train in the wrong direction.Yeah, that is véry stupid. This train was fifteen minutes too late and we stepped out when we found out this wasn't the right train. We waited for another train to go back, but forgot to buy new tickets. Luckily, nobody found out (uhm...although, I was talking very loud about this in the compartment). We decided to go home and today, we'll try again this afternoon.
