My son: "Do you think my eyes are shaped like an eagle's eyes?"
Looking at him closely, "Wow, actually they are. That's pretty cool."
My son, looking a little sheepish and happy, "I'm kind of proud of that!"
My son, again: "Let me look at your eyes, Mom."
He stared hard for a few seconds.
Me: "What do you think? Do mine look like an eagle's eyes, too?"
Him, trying to suppress his giggles: "Uhm, Mom? Yours kind of look like a duck eyes!"
Me: "What?! A duck?!"
Him, unable to hold in his laughter anymore: "I know, Mom, I don't really think I'd want duck eyes either, I'd be kind of embarrassed about that!"
And then he whispered under his breath: "I bet ducks would really like you, though."
