For the past four years I have been renting an in-law apartment in an old farmhouse owned by a young couple. During that time we have become friends and I have never given them a reason not to trust me. They took back one of the rooms I had upstairs for storage a couple of years ago and there was never any reason to lock that door, even though it accessed their side of the house. I have never opened that door or gone in there and I NEVER have people over. They know that. All of a sudden there is a fresh, new hook and eye on the door and it is locked. I can see it since the door is warped slightly. This is not an issue of whether I have literal access or not but one of trust. I have NO reason to go over on that side of the house and in turn, they have NO reason to lock it. I just makes me feel uncomfortable. I see the situation from both sides. They want THEIR side separate, private and secure but from what? I would rather not ask them outright since it may sound as if I tried the door or am thinking about it. Wondering why and all of that. Trust is a big thing for me. I have spent a lifetime of building a good reputation and of being honest and what most people would consider sane. Maybe it is because of my gender, age and the fact that I am a Vietnam vet. Maybe they have visions that I will go over there and kill them as they sleep. Who knows!
