It helps to know how a name is pronounced when we talk about you. I thought "Rapaire" was "repair" too. You're still gonna be shortened to "Rap".

McGrath, when I heard him on Max's Mudcat radio show way back in the dark ages, was "McGraw".

For years, I thought "epitome" was "eppi tome" -- rymes with "peppapoem", because I only ever heard it in my head when I read it. The first time a thing like that come out of your mouth when you're in a group of folks who know better, you realize that it's good to know pronunciation.
