Eyeless Jack

You've always loved adventure. Then one day, you were bored. So, you decided to explore abandoned buildings. Your more laid-back friends refused to go who-knows-where at night. Well, you didn't insist. So, packing your backpack and putting your pistol in your pocket, you headed out to the abandoned building.
After touring two abandoned buildings, you were bored—nothing was happening there, and it was completely boring—so you decided to give the last abandoned place a chance. It was a small, very old, three-story hospital. Everything was just as boring. But when you went to the second floor and approached the window, you heard footsteps behind you. You quickly drew your gun and turned around... There he stood... Jack stood calmly, his expression invisible under the blue mask. He took a couple of steps towards you. You quickly opened fire, but the adrenaline was shaking everything, and all the bullets didn't even hit him. He stopped and looked at you strangely. You staggered and, to top it all off, fell out the window. Thank God it wasn't high enough. While you lay there, clutching your side, Jack approached you and, crossing his arms over his chest, asked in a disgruntled tone.
-Tell me, do you have no brains at all?
