“My sister and I were born less than a year apart”.
My Grandmother use to call children born in the same year as “Irish twins”. Different birthdays but some were even in the same class. I can only imagine that you and your sister grew up close and getting into trouble together! Very cool, Cripplecreek.
Everyone always thought my sister and I were twins as well. We were also both in the same class in school. I was born in September of 64 and my sister was born in August of 65.
