Lost key :-(

My troubles never seems to stop this week. Tonight I lost my house key. Had gone out shopping in the old city of Lausanne with Regis today afternoon. But, everything is so expensive here - dint end up buying much. Then in the evening some friends came over, and I went out with them for dinner at their place. And reaching there I realized I did not have my key in my pocket. Searched a lot all around the way and everywhere. dint find it. And hence spent the night outside my room, in the drawing room couch.
