if you design very intricate redstone contraptions in your head, then test them in your head and realise they don't work
When you sprinkle crushed up chicken bones on your garden hoping it will grow instantly...
When the sound of sizzling bacon scares you half to death and you blurt out "CREEPER!"
When you keep your eyes to the ground when traveling the streets at night, because you don't want to look up and accidentally see that one lingering Enderman.
When you walk down the street and think 'I might build that later'
When you drive by a Christmas tree farm and think "Hey! They stole my design!"
When you find yourself counting the floor tiles, trying to find the exact center.
When its foggy and you think of pressing F
When you close the door behind you and look for the 'private door' message rather than reach for your keys.
When you start having wet dreams about DanniDorrito!
