Natalie says to Clark today: "Baba, do you like the tie I made for you?"
Clark: "Yes, I love it!"
Natalie: "Then how come you don't wear it to work?"
Clark thinks about it: "Well... because I will be the only one to have such a nice tie and then everyone will want one, too."
Natalie (nodding thoughtfully): "Ya... and I can't make one for everyone because then I will be so tired."
