I listened to an interview recently with a man talking about his guide dog. He explained that if the dog does what it's trained to do, but not what he wants it to do at that moment, he always praises it before correcting. When he wants to use a different subway exit than usual, but dog tries to take him to the usual one: "Good boy! Find left."
That's how I feel when I have to add custom inflections so Rails will let me use singular 'quota' and plural 'quotas' instead of plural 'quota' and singular 'quotum'.
