I'm Jason, and I'm 18. I've had this gnawing backache for years, and it's only gotten worse. So, I decided to do something about it. I picked up a part-time job, saving every penny to buy a new bed and mattress.

Asking my parents for help wasn't an option. They've always prioritized my younger half-sister, Ashley, and our foster siblings, Natasha and Everett. It's been five years of feeling invisible, but I've learned to cope.

But, yesterday, my life changed forever.

We were having one of those rare family dinners with my grandparents. Just as we were digging into Grandma's famous lasagna, my phone buzzed. The courier was here with my mattress.

"Excuse me," I mumbled, pushing my chair back.

"What now?" Mom huffed, clearly annoyed by the interruption.

I ignored her and went outside to meet the delivery guy. The sight of the mattress made my back feel better already. I tipped the guy, thanked him, and wrestled the thing into the hallway. When I got back to the dining room, the tension hit me like a wall.

Mom stood there, arms crossed, her face a mix of annoyance and something I couldn't quite place.

"What the hell, Jason? You know we're all saving money for Ashley's car. Return that mattress immediately!" Mom's voice was sharp, cutting through the awkward silence.

Ashley, sitting pretty at the table, chimed in with her signature whine, "Why does he get a mattress when I need a car?"

I took a deep breath. I'd been waiting for this. "Mom, I bought this with my own money. I've been saving for months. I need this bed for my back."

Mom's eyes narrowed.

"That money should be going towards something the whole family needs. Ashley's car is a priority."

I could feel my frustration bubbling up. "A priority for who? For you and Ashley? I've been working hard to afford this. My back is killing me, and I need a decent bed."

Ashley's pouty face twisted into a scowl. "You're so selfish, Jason! I can't believe you're doing this right now!"

Before I could respond, Granddad cleared his throat. The room fell silent. He'd been watching the whole exchange quietly, his face growing darker by the second.

"Michelle," he said, his voice steady and calm, but with an edge that made everyone listen. "We know parenting is hard, but what I'm seeing here is beyond that. Jason's been working hard and needs this bed. What's more, your behavior is unacceptable."

The sting of betrayal was sharp. My own parents undermined me in front of everyone, making me look like a monster. It was like they didn't understand the pressure I was under, trying to balance everything for Ashley and the foster kids.

Mom's face turned beet red. "Dad, you don't understand. We've been trying to save for Ashley's car for months."

Granddad didn't budge. "Michelle, we were going to gift you an apartment as a reward for all you do. But after seeing how you treat Jason, we've changed our minds." He looked me in the eye and gave a curt nod. "We're giving you the apartment instead, Jason."

I was shocked speechless.

"Dad, you can't be serious!" Mom snapped. "He's just a kid. He doesn't need an apartment."

Grandma, who had been silent until now, finally spoke. "He needs a place where he can feel valued and not constantly overlooked. You've been neglecting Jason for far too long."
