You can idealize childhood all you want, but I’m glad I’m a grownup, especially when the subject of birthday parties arises. These things can be minefields.

For example, Lucy just found out she wasn’t invited to a classmate’s party. Her school has a rule that says all the girls in class have to be invited, but not everyone obeys it. And during summer, who’s going to know?

Ah, but kids do find out—even when school’s not in session. It was rough for Lucy to hear she didn’t make the cut—particularly since the girls who did are the same four she plays with everyday at recess. When they let her, that is. She once came home in tears because the group’s ringleader, a child who’s often hard on Lucy, told her they were all playing separately that day. It was just a ruse to get Lucy to buzz off.

This is why, as Lucy’s ninth birthday approached, I was feeling torn. I wanted her to have a party, but I didn’t really want to have some of those kids over to my house. What if Lucy wanted a piñata? Could I trust myself with the club around the ringleader in particular? Okay, I’m kidding. Why would I thwack a child who isn’t stuffed with delicious candy? (Still kidding!)

At any rate, when school starts again, I’ll help Lucy to find more friends she can count on. For now, though, it’s all about helping Lucy turn 9 and realize she’s loved. This is where it’s really handy that Lucy has a bunch of cousins. Our family is crawling with them, and they all adore Lucy because she’s funny and crazy and can be counted on for instruction in all the important things in life.

So I asked my brothers and sisters if they’d be up for an impromptu surprise party. They were, of course, as was my mom, who asked if we could have it at her place, because my dad isn’t quite up to climbing the dozens of steps up we have. But this was even better because it meant I wouldn’t have to clean and someone else would have to inflate all the balloons. Of course I said yes.

We set the party for 6:15 on Saturday night. Well before that, the call came from my sister. They were ready for us. We weren’t doing much of anything, so we packed up to leave, with the understanding that I would send a text message when we got to my parents' driveway.

That seemed risky to me, though. My parents live on a narrow street lined with enormous fir trees. I’m not totally clear on how text messaging technology works, but it seemed to me that the text fairies who undoubtedly are used to deliver these messages might get their wings caught up in pine needles. We might surprise them with our arrival, rather than the other way.

So I decided to send periodic texts during the entire ride to Grandma’s house, so that they’d have the best chance of reaching their destination. And of course, I had to use code.

“The pig has left the poke!” I wrote, as soon as the kids were buckled into their booster seats.

My sister replied almost immediately: “We have rehearsed. We are ready. It is really hard to wait.”

We drove a few blocks, past a park filled with trees. “The pig is in the woods,” I wrote.

Her reply: “We are still ready and very excited—almost to the point of agitation.”

We made it through the woods and onto the next landmark. “The pig is on the bridge,” I reported.

The reply: “We have popped four balloons while waiting.”

Before I could respond, another message: “Make that five.”

I looked over at Adam in the driver’s seat. He was obeying the speed limit, as usual. I was feeling agitated myself, like maybe my head would pop. The car rolled onward, though, and my head remained intact. I sent the second-to-last text: “The pig is on the point!” This meant we were a half-mile from the destination.

The reply came almost instantly. “We only have two balloons left. Better hurry.”

Then we were at my parents’ driveway, and I sent one last message: “The pig is in the blanket. The pig is in the blanket.”

My sister’s reply arrived: “We have one balloon.”

And then Lucy was in my parents’ kitchen, where the cousins were hiding. They hopped out at once, releasing a single yellow balloon into the warm summer air. “SURPRISE!” they yelled. “SURPRISE!”

Lucy was, indeed, surprised. She spun around in glee as they sang happy birthday to her, and even though I knew what was coming right down to the number of intact party balloons, I felt my eyes prick with tears.

It wasn’t surprise that got me—it was the opposite. It was the knowledge that I could count on other people to love my kid. I’m talking about her cousins, but also her aunts and uncles who blew up balloons, set up a string maze, and organized everything for a round of the family classic, The Chocolate Game.

Being reminded of that every so often, especially after a bad birthday-party incident, is a gift a mother really needs.
