I was a pre-med student because my mother was a nurse and she wanted more for me. Not better — more. She would say that with a straight face and I believed her. Medicine was never my dream. It was hers, handed to me like something I was supposed to carry.

Junior year of college, I signed up to volunteer at a county hospital on Tuesday nights. I nearly didn't go the first night — I had a paper due. But something made me go.

There was an elderly woman in bay four, alone. Her family lived in another state. She'd had a fall. I sat with her for almost two hours. I held a cup of water to her lips. She didn't say anything. She just reached out and held my hand. And in that moment I thought: this is it. This is the whole thing. Not the salary, not the prestige. This.

I walked out of that hospital at midnight, stood under the parking lot lights, and called my mom. I told her I wanted to be a doctor. She said, "I know, mija. I've always known." She was right. She was just waiting for me to figure it out.

Fifteen years later, I run an ER. Every Tuesday, I still think about bay four.
