Found this beauty in Kaunas, Lithuania. I almost got locked inside this building. Went inside through an opened door like it's my own and when I started going back after half an hour, I've heard locking sounds.
At that moment I had a choice. Not expose myself and risk being stuck in and abandoned building 1000km away from home. Or to run to the door, knock on it and risk having trouble with the police.
It's one of those split second decisions where your gut feeling knows what to do. There's a bit more to this story but this is not the place to tell it.
