Each day I do struggle with one thing. The key to the building my apartment is in, is shaped as you would anticipate the key to the actual apartment would be shaped. Then the key to my actual apartment is shaped as you would expect the key to the building would. So everyday, after years of keys conditioning, I try to push in the square key into the front door when I shouldn't. I have lived in this apartment for five months, when will I overcome my key prejudice?
