My great grandmother was the same way. And I've got an uncle on my dad's side who's only 5 years older than me. Myranda would be tickled pink if I met someone and had another little sibling for her. Jill keeps saying, "Forget it mom!"
Yeah, it is really funny when I talk about granny, and mom's cousins talk about granny. They
know my mother is their first cousin, but assume that since I am their age, that she was my grandma, not my greatgrandma. Heck, mom has first cousins younger than me!
Granny had 8 kiddos in all ~wow~ I cannot imagine having children at the same time my children are having children. The age difference between my grandpa and aunt Trudy (his sister) is 26 years. Aunt Trudy is younger than my mother.
