***So I answered the way I always did when that subject came too close.***

“Sweetheart, your dad does not know where we live.”

Adrian’s face fell slightly, and I hated how quickly I continued.

“And even if he did, I’m not exactly betting on him becoming Father of the Year through anonymous stationery.”

That earned half a laugh.

I slid his pancakes toward him.

“Maybe it’s an old teacher. Maybe it’s one of my friends being weird. Maybe you’re part of a very low-budget spy operation.”

He smiled, but barely.

***Then I made the joke I should not have made.***

“Besides, these envelopes have money in them. Your father would never.”

That time, Adrian genuinely laughed.

Only for a moment.

Then he looked down at the card again and became quiet.

After that, we stopped trying to solve the mystery aloud.

The envelope simply became part of his birthday.

Like candles.

Birthday photos.

Like me pretending not to get emotional each year as my little boy grew taller, his voice deepened, and he moved farther away from the child who once asked whether worms had mothers.

Then last week, Adrian turned eighteen.

***I had a weird feeling before I even woke him up.***

Maybe because eighteen feels different.

Final.

Legal.

Adult.

Like a chapter is closing whether you are ready or not.

The night before, I stood in the kitchen frosting the cake he had specifically requested “not to look emotional,” with an ache in my chest I could not explain.

The envelope arrived that morning.

Same size.

Same plain white paper.

Same careful handwriting.

Adrian saw it on the table and gave me that familiar smile from childhood.

For one second, I saw the six-year-old boy again.

“There it is,” he said softly.

He picked it up and turned it over.
