So what was it, actually, that Period did that annoyed Comma so? It was the fact that whenever Period said "Hey, here I come", things would stop. Immediately. People would have to begin afresh. Pick themselves up, don an upper case and continue. This was totally against Comma's firmly held belief - never make people change their cases unless they really really want to. Lower cases were lighter to lug around, and merged well with others. Upper cases? Well, now they were a different ballgame altogether - they towered over others, gave others an inferiority complex, and even sprouted shoots and leaves just for effect. No, upper cases were definitely not on the list of Comma's favourite things. The last time an upper case had stood next to Comma in the queue, it looked down its nose at Comma, sniggered, and said, "I represent Proper Noun".
