Before I was born my parents were planning on naming me Penelope and calling me Penny but after I was born they changed their minds. My mom had an aunt who's dog was named Penny. Since we spent a lot of time at this aunt's house my parents kept teasing me that the dog and I almost had the same name. I never minded because I like the dog and thought it would have been kind of cool. I think there might be issues between your wife and mother.
