7. Height
The first time Conan complained about his height was when he could not reach the counter to get his orange juice before Kogoro got it.
The next time he complained, was when Ayumi had to help him get a book from a shelf he could not reach at the library.
And the last time he complained… was when reality hit him too hard.
He had always been short when growing up as Shinichi. Shorter than the average height in class. He only managed to reach the average height when he entered high school.
Realising how short he will continue to be, Conan sat down and drowned himself in cups of coffee in an amount too much to be healthy.
