Her shoes shoved haphazardly into the purple bin, Sierra scurries to the remarkably high jungle-gym and climbs in, waving at me each time she reaches a window on her hidden journey to the big slide back down.
Their Happy Meals finished, Chris and Chris whoop and climb into the plastic balls as Sierra emerges from the slide looking slightly confused. But then her 3-year-old eyes find mine a few tables away and she giggles.
Mommy, however, is now the least interesting person at McDonald's. There are boys in the ball bin, and to the bin she goes.
She stops at the entrance and gives them a quizzical look. "What's your name, little girl?" asks one of the Chrisses, who appear to be about 5 years old.
What's your name, little girl? WHAT'S YOUR NAME, LITTLE GIRL?? I glance three tables down at the other mother, who appears to be there with Christopher, her son, and Chris, her son's friend. She keeps reading her paper.
"What's your name?" Christopher asks again. Sierra drops her chin to her chest, then raises her eyes to give him a look, but still she doesn't answer. If that were Jennifer and Jenny in that ocean of balls, she'd be swimming on in.
Just as I start to suggest that she tell them her name, a ball comes whizzing from the bin, missing its target but removing all doubt.
There is flirting going on here.
I can safely list that as Shock No. 371 on my list of things other mothers failed to mention when they were doling out that 14 tons of advice when I was pregnant. Shock No. 1 was that babies poop like a car backfiring when they're first born, shooting the contents of their newly opened bowels across the room if you and your new white nursing gown aren't in the line of fire to stop it. The fact that missing a square on a waffle while dispensing the syrup is a capital offense was No. 298.
I expected poop. I peripherally expected confrontations about breakfast food. What I didn't expect was that I would hyperventilate about boys before she was 10.
Yes, I'm reading too much into this, this play of innocent children. But then another ball goes flying; a cry rings out.
"Mommy! He hit me in the nose with a ball!" Sierra cries as she stumbles out to the table.
"Christopher, don't throw the balls," offers the other mom.
Sierra, who normally would wring a good 10 minutes of crying and comfort from a ball-in-the-nose incident, returns to the bin dry-eyed for more, um, interaction.
But she's still wary of these perfectly normal boys. She doesn't talk to them, she doesn't play with them. It's so unlike her. She can tell they're different from the girls her own age she's used to playing with, and she doesn't understand.
I can see her almost shrug when I tell her it's time to go, and for a change she doesn't cry. She's tired of trying to figure it out.
She heads inside the monstrosity for one more trip down the slide.
"Get your shoes, Sierra," I say as she steps out onto the cushy walk.
The Chrisses, who are sitting on the edge of the slide after following her down, look as if they've seen Santa Claus.
Their eyes wide, they turn and grin at each other.
"Her name is Sierra," says Chris.
"Si ... erraaaah," Christopher sighs, then swoons back onto the slide.
They collapse into giggles as Sierra rolls her eyes and grabs my hand to leave.
Heaven help me.
