Nothing to worry about

An unprovoked conversation heard at breakfast:
Sam: ...Mommy always comes back for you. She won't be there all day. She's going to leave. But don't worry, you'll have 2 teachers and lots and lots of friends. When you are ready to, you can laugh and laugh and laugh and play with all of your friends all day. You'll like school, Noah.

Interesting side notes: This was directed toward Noah, not Aidan. It was also entirely without any preceding conversation about school, Noah's, Sam's or Aidan's. Noah listened with rapt attention. And responded with "OK Sammy"
