My silly little girl...

Amy: Mom, I made a new friend today.
Me: Really?
Amy: Yeah, she's my best friend.
Me: That's great. What's her name?
Amy: I don't remember.
Me: (quietly chuckling)
Amy: Mom, why are you laughing? She really is my friend!
Me: I know...but you don't remember her name?
Amy: No....but I remember she's a GIRL! (smiling proudly!)

Ha ha! And that is the beauty of five-year-old friendships! No drama, no pretense, no commitments...just "friends"!
