On Christmas morning, Amber found a beautifully wrapped gift under the tree addressed to an unknown woman. Upon confronting her husband, Carl, she learned he’d packed the gift. Who was the unknown woman? And why did Carl buy a gift for her?

This Christmas started as the worst one of my life.

Christmas Eve had been magical. We’d baked cookies, sang carols, and laughed until our sides hurt. My husband, Carl, even danced with our son, Logan, twirling him around like a tiny ballerina.

Logan went to bed with the excitement only a five-year-old could muster, dreaming of Santa’s gifts, while Carl and I stayed up sipping cocoa and admiring the twinkling lights on the tree.

By morning, snow dusted the ground like powdered sugar, and everything seemed perfect. Logan and I were already in our festive pajamas, and he was super excited to open the gifts.

“Mom! Can I open this one first?” he squealed, pointing to a brightly wrapped box with his name scrawled across the tag.

“Let’s wait for Dad,” I said, glancing toward the kitchen where Carl stood by the counter, sipping his coffee.

He looked unusually tense, his shoulders stiff as he avoided my gaze.

“Carl,” I called out, “Logan’s ready to dig in.”

Carl nodded but didn’t move. His behavior was odd, but I brushed it off because it was Christmas.

We settled onto the floor, and Logan ripped through his first gift with all the enthusiasm a five-year-old could manage. He gasped as he uncovered the toy truck he’d been begging for.

“Santa got it right, Mom!” he yelled, holding it up like a trophy.

“That’s so cool!” I chuckled.

But all of my happiness suddenly faded as my gaze landed on a big, glittery box under the tree. I hadn’t seen it the night before.

As I picked it up, I noticed a small note on top of it.

It read, For Debra, with love. You’re my only one.

I felt a knot tighten in my stomach.

“Who’s Debra?” I whispered, staring at the note as though it might somehow explain itself.

That’s when I heard Carl’s voice. His face was pale and his eyes widened as he looked at the box.

“What are you talking about?” he stammered.

I held the box up, shaking it slightly. “This. What the heck is this, Carl?”

Before he could answer, Logan piped up, beaming with pride. “I helped Santa! I found it hidden in Dad’s basement yesterday. I thought he forgot to put it under the tree, so I brought it up here at night.”

I whipped my head toward Carl, my heart racing. “Logan found this in your basement? Who’s Debra, Carl? Why is she your only one?”

Carl looked at me with wide eyes but was unable to explain anything.

“Am-Amber,” he stammered. “Debra, she’s my… it’s not what you think—”

“Oh, I know exactly what I think,” I said as tears started trickling down my cheeks.

I cried as I thought about how Carl had broken my trust, that too on such a special occasion. The man I trusted with everything had bought a gift for another woman. And not just any gift.

A gift addressed to “my only one.”

Suddenly, I felt Logan’s small hand tug at my sleeve.

“Mommy? Are you okay?” he asked innocently. “Did I do something bad?”

I quickly knelt down, brushing his hair back.

“No, sweetie. You didn’t do anything wrong. Go play with your new toy in the bedroom for a minute, okay?”

Logan hesitated but eventually ran off, leaving Carl and me alone.

I turned to Carl and looked at him with a serious expression, my hands folded.

“Explain,” I said. “Now.”

Carl looked like he’d just been caught in a lie he couldn’t talk his way out of. His shoulders slumped, and he shook his head while looking down.

I braced myself, half-expecting him to admit to an affair.

“Debra,” he began, “is… my sister.”
