First, of course, she must think to herself, "I could sure go for a car ride right about now..."
Then she realizes that she needs to get herself and her parent of choice ready for the car ride. Usually I'm the parent of choice, not because she's showing any kind of favouritism, but only because I'm the parent that's home 100% of the time.
So! She runs and gets her shoes on. Then she collects her mother's shoes and so kindly brings them to her, shouting...
"Mama! Mama... shoo! SHOO Mama!!!"
Then comes the demand... "Caw? (Car, of course) Caw Mama! PEEEES!" At this point, because I have no intention of going anywhere, I just smile at her and say, "oh, you're so cute Lena." And then I get back to whatever it was I was doing. She doesn't give up though, and for the next fifteen minutes she's bugging me for the "caw."
Sometimes she likes to dance as she begs.
"Uh... Mama...? Caw? Caw peeees?"
And sometimes she forgets for a moment or two about the car and spends a few moments practicing supermodel poses.
Eventually she remembers though. And then she gets bossy. "C'MON Mamma!!! Caw!"
Here is the look of disappointment washing over her face as she watches me put my shoes away, and hears those dreaded words, "Sorry Lena... we're not going for a car ride."
So, in typical little girl fashion, she takes off as dramatically as possible, runs to the living room, throws herself at the couch, and prepares for a good ol' sulk. 
Ahh... it's almost irresistible. But I'm very strong. What you can't tell from looking at these pictures, is that she's making a little "hmpf!" sound every five seconds.
Ha! Look at that face. If her father had been around for this, you can pretty much guarantee she'd have gotten that car ride, and probably wormed her way into getting a pony too.
