Phone rings. “I cant read my prescription” “was it from a test we did” “yes” “ok found it what’s the problem” “I cant read it” “ok well the photo copy I have here is perfectly legible for anyone that needs to read it” “well I cant read it” “well you have the original and I have a photocopy and I can read the copy fine. Anyone that is making anything up will understand it so don’t worry. If they have any problem get them to call me” “well I cant read it” “ok why what’s the problem with your original?” “The first box its got a squiggle in it” “umm that’s infinity” “what” “its infinity, it’s the symbol for infinity” “what’s that?” “The symbol is for infinity its called a lemnsgate or lenmsate or something I cant remember but it looks like an 8 on its side right?” “Yeah but what is it?” “it’s the symbol for infinity, don’t worry anyone that it making up the prescription will understand” “what is it?” “it just means infinity” “BUT WHAT IS INFINATY” “pardon?” “What is infinity?” “what’s infinity?” “Yeah?” “Well in means goes on forever, no end sort of thing” “I don’t understand. What is infinity? ” “Well in this case you really don’t need to, just don’t worry about it. It all written out correctly you just need to hand it in to be made up” “but I don’t understand what’s in the box” “its just the symbol for infinity and it looks like an 8 on its side. Its written out in standard notation so the people making the lenses knows exactly what’s going on.” “Shall I write that word on it?” “What word” “infinity” “NO don’t right anything on it al all or it could get made up wrong. Just go and had it in” “well if you are sure its ok”
