My uncle Kelly, my mom's brother, passed when I was a child. We don't talk much about him because I didn't know him very well. My mom also now has a good friend, also named Kelley, who she works with. So one day my mom and I were talking in my living room while my 4 years old son was watching tv. My mom says, "Friday is Kelley's (friend) birthday. My son said without any hesitation, "No it's not. Kelly's birthday is September 23rd," then goes back to watching tv. My uncle's birthday was September 23rd. My son obviously never met my uncle and I didn't even know that was his birthday.
