When I was little, I didn't understand the concept of years changing how old people were. I thought that since I was born in January and my little sister (by four years) was born in February, that was what determined our ages. When I learned my Grandma was born December 23rd, I exclaimed, "Grandma! You're older than Jesus!"
She didn't like that.
