The Age of Pet Peeves

I have a very dear friend who has, what I consider to be, an odd pet peeve. It drives her crazy when a person responds to the question, "How old are you?" with "Almost twelve," or "Just about twelve," or anything similar in nature. Her view is that, if a person is almost twelve, they are not yet twelve so their response should be a simple "Eleven." I, personally, find the former responses to be more semantically informative. However, as the person responding to the question, I suppose it does depend on how old you are and how much you want to reveal about your age. I certainly would not respond, "Almost forty," though my thirteen-year-old son would proudly say, "Almost fourteen."
