A friend took her daughter through the Starbucks drive-thru for a hot chocolate on her birthday this weekend. She let her daughter tell the drive-thru speaker that it was her birthday.
"Happy Birthday!" the drive-thru speaker said. "How old are you?"
"I'm four," the daughter said.
"Honey, you're five," my friend corrected her.
"No," the daughter said. "I'm four."
As they pulled up to the window, my friend asked her daughter why she though she was still four.
"Mommy," the daughter said (a little exasperated), "I'm four until my birthday party starts. Then I'll be five."
If those are the rules, I'm not having any more parties.
