Me: Hey, Alex, I'm the best!
Alex: Yeah, Heather, I fink you are the best!
Me: Hey, Alex, Miki is second best!
Alex: *giggles* yeah, Miki is SECOND BEST!
Me: Alex, I'm going to get you and Iris some ice cream. Because I'm the best!
Alex: Yeah, Heather, we're best friends, too!
Me: And what's Miki?
Alex: Second best! Because I fink you are the BEST!
(I may or may not have told the kids that Miki might try to steal their ice cream because that's what second best does.)
