A dad is carrying his (I'm guessing) four-year-old daughter by a mailbox in the nabe.
"Do you want me to mail you?" he asks.
"I'm not a letter," she replies with full and sincere indignation.
Bonus cute kid story
On the SRT a month or so ago, a family is riding. Mom's sitting with the little boy, and the little girl is sitting opposite with dad.
"Mom, dad won't talk to me!" protested the girl.
"Mom makes that complaint about me all the time," said dad, who then offered this mock apology.
"I'm sorry. Am I not entertaining you? Would you like me to stand on my head?"
"That would be silly," pronounced the daughter.
But then she started to giggle.
