Natalia: Mom, I want to send something to S~ (one of her best friends). I don't remember what it's called.
Me: Send something?
Natalia: I want to tell him something.
Me: An e-mail?
Me: An sms?
Natalia: No... Not that...
Me: Do you mean a text?
Natalia: No! Not that!
Me: I don't know what you mean, honey.
Natalia: You know, paper! That you write on! What's that thing called?
Me: Um, A LETTER?!!
Natalia: YES! THAT'S IT! (Silence.) Um, Mom? How do letters get to people?
Me: (Realizing that she truly has lived most most of her life here...) Mailmen deliver them.
Natalia: (Trying to figure out how that would work. Keep in mind that we've never used the unreliable Russian postal system to receive or send mail -- other than our college alumni magazine -- since moving here; the only mail we get is through the Fed Ex pouch at Chris's office). Hmm... How do they know your password to get the mail in your box?
