Here’s this week’s Smartmom from the Brooklyn Paper.

Smartmom hasn’t cried yet. And she’s worried that maybe there’s something wrong with her. In about two months, she and Hepcat will be attending the Oh So Feisty One’s fifth-grade graduation from PS 321.

And she hasn’t shed even one tear.

Maybe it’s because Smartmom has been through it before. When Teen Spirit was in fifth grade, Smartmom found herself getting misty just about every day.

One day she couldn’t contain herself when Teen Spirit’s class sang “In My Life” to the parents during Parents as Reading Partners one Friday morning.

The sobs just erupted and wouldn’t stop.

Later, at the dearly departed Mojo Café, she tried to tell a friend about it and she burst into tears, again.

“I’m sorry,” she weeped into her cappuccino. Her friend, who had a pre-schooler, didn’t have a clue why she was so emotional.

Smartmom cried because it was hard to face the fact that her firstborn was growing up.

She cried because the middle school application process was frustrating and dispiriting.

She cried because she had no idea how or when she’d gotten so old.

Smartmom went to Teen Spirit’s fifth-grade graduation fully expecting to cry her eyes out. She didn’t realize that the graduation ceremony would be a marathon of speech making by local politicians, like health nut Marty Markowitz, who made the kids do jumping jacks.

On an excruciatingly hot day in June, the graduation ceremony lasted almost three hours and Smartmom found herself getting a little antsy. But the tears did come during the slide show.

Later, the tears came like the fountain in front of the Brooklyn Museum, when, at the end of the ceremony the kids turned around in their seats and sang that famous song from “Rent”: “Five-hundred twenty-five thousand, six-hundred minutes, 525,000 moments so dear. Five-hundred twenty-five thousand, six-hundred minutes, how do you measure, measure a year?”

Waaaaaaaaaaaa.

Yet here it is, March of OSFO’s fifth grade and Smartmom’s eyes are as dry as the Sinai. What is wrong with her? To make it worse, she’s seen more than one friend get emotional.

Smartmom’s friend, the co-president of the PTA, let it rain at a yearbook meeting at Sweet Melissa’s. She cried again going through old photographs for the book’s “The Way We Were” section.

But still no tears for Smartmom.

Smartmom knows it’s partly because she’s been through it before. Sure, but that’s no reason to get nostalgic about an important milestone in OSFO’s life.

Smartmom may just have to face that she’s ready to leave PS 321. For Buddha’s sake, she lives right around the corner from the school and Diaper Diva’s daughter will be starting kindergarten there in 2009.

Eleven years is a long time. Maybe she is ready to have two kids finished with elementary school. No more choice times, parents as reading partners, writing celebrations, drop offs, pick ups, working on the school’s annual poetry magazine, hanging out with mom friends at Sweet Melissa’s, pot luck dinners, parent/teacher conferences…

Omigod, they’re coming. A tear just dripped onto the keyboard of Smartmom’s MacBook.

Smartmom hopes they keep on coming at OSFO’s big ceremony in June. She knows there’s going to be a slide show. She hopes they use a tearjerker by the Beatles as the soundtrack. And when the kids sing, she hopes it’s a really smaltzy song like “Seasons of Love.”

Maybe just looking at OSFO all dressed up on that day, on the precipice of this big change in her life, will be enough to instigate Smartmom’s big cry.

Uh oh, here they come. Quick, where’s the Kleenex?
