So we were taking a train from Barcelona to San Sebastian and it took forever. The pain of the duration was alleviated somewhat by the company we had: an older couple from Oregon who were getting ready to do the Camino de Santiago. We talked to them almost non-stop for like 7 hours.
After they got off in Pamplona I passed out. Had been reading my book before I fell asleep and stashed in under the armrest of my seat. I wake up and we get to San Sebastian like 15 minutes later.
As we are walking to our hostel I realize I never grabbed the book. Then I realize my passport, train pass, and loot are inside. We book it back to the train station, I talk to the guy and tell him what happened and he gets on the horn.
I´m listening attentively to his conversation and hear the glorious words "está encontrado" (its found) and do a little jig. Turns out that someone found it before the next station and it was waiting there. So we hop on another train that was just then pulling up, go to Irun, and when we get off the train there is a train employee standing there with the book and all its important contents in hand. Total time of separation from valuables ~45 minutes.
