““One annoyance is people’s seeming inability or unwillingness to differentiate between the number zero and the letter “o.” I’ve had conversations with telephone operators who have told me that I can reach my party by dialing, for example, 31o-3o55. Sometimes I’ve asked, “If I follow your instructions, by dialing the letter ‘o’ instead of the number zero, will I reach my party?” They always answer no and that I must dial the zero. Then I ask, “Why did you tell me ‘o’ when you meant zero?” Our chitchat usually degrades after that. It’s not only telephone operators. How many times have you heard a student or teacher say, “He has a 4 point o GPA”? I””
