How I lost my bullion bar

A few weeks ago, I got a large gold bullion bar from a distant relative of mine. I travelled five hundred kilometres by train just to get the gold. My distant cousin lives in the mountains, and it was nearly summer, so there were hundreds of passengers on the train. They were going on holiday. But I was thinking of something else. I was imagining myself buying a wonderful brand new motorcycle. I arrived at my cousin"s place in the evening. We had supper and then went to bed. We spent the two following days hiking in the mountains. He said that it"s the first time I had visited them, so I must see the beauty of the place. I also got to known many distant relatives I had never met before: two aunts, their husbands and children. On the third day, I was finally given the present. My cousin told me to use the money wisely. He actually hoped I would pay for a language course as I"m not very good at speaking foreign languages, but I didn"t tell him what my real plans were, of course. I packed my gold bullion bar and left the village. I was really tired and the train was late. The first thing I did when I entered my compartment was lie down and fall asleep. I couldn"t help it! When I woke up, my bag was gone. Who stole it? Was that anyone I knew?
