Handbags   (The sad, the bad and the ugly. Non-productive stuff here.)

"It turns out that this unusual convention was a bit of an accident. In Old and Middle English, the word for “I” was closer to its German cousin, “ich,” and it was often spelled “ic.” At this point, the word was not capitalized. However, the pronunciation changed over time and so did the spelling, losing the consonant c. At first, the new word, i, was left lowercase. However, it began to grow taller than other words. It grew for a silly reason: a single letter looks bad. Look at it: i. How sad. By the time Chaucer wrote The Canterbury Tales in the late 1300s, I, the personal pronoun, was slightly taller than its lowercase equivalent. From that point on, it was typically capitalized."
