When we came back from SO's folks' house in Auxerre on 2 January, I locked the house and came up on the bike alone, having dropped my 'too-cold-for-me' SO at the train station. Friday last, I again go down there alone on the bike, twelve hours ahead of SO, so that I can heat the house, get a fire going etc. Arrive in front of the house, off with helmet, bike onto stand, and walk up the three steps to the front door. Key in, but can't get it to turn, and a push on the door sees it swing open. 'Hmm, "mother-in-law" must be there', I think, although it seems strange that her car isn't in front of the house. When I call out, however, my only response is silence. Nope. 'maison' is empty. Yep, I had left the house open, unlocked and empty, two weeks before. <sweats bullets>
