I've lost my wallet twice to pickpockets, once in New York City, once in Krakow, so I can testify that that you are presenting a recognizable portrayal of the stages of emotion one goes through, though I think your introduction of Gaudi into the mix raises this above a mere slice of life. My one reservation is your inclusion of Spanish. It is a matter of taste, of course. For every reader who finds that the Spanish adds an additional layer, there may one or two who don't know Spanish and who feel shut out by words they can't follow. I usually hesitate before using a foreign language, unless the terms have been adopted into English or are pretty obvious in terms of what they would mean in English. But that decision is up to you.
