When I was very small, I couldn't deal with the fact that there were "number words" that weren't definite. I mean words like "a couple", "a few" and "several". I pestered my mother about this until she told me that "a couple" was 2. Eventually I made up a whole system where "a few" was 3, and "several" was 7. It took me a while to come to terms with the fact that people were sometimes just talking about an unspecified number!
