When I first heard an explosion three years ago, it was an Iskander missile, and I didn't sleep all night after that. It was really scary. Now, after three years of constant shelling, the fear is gone. All what remains is this first immediate reaction when you flinch at the explosion or jump out of bed and then lazily grab my laptop and go into the hallway. Like nothing happened. It's very strange, and there's nothing you can do about that first reaction.
