What is the narrative’s thesis statement?

I’ll never forget walking into that hospital for the first time.

My parents had been telling me that I needed to volunteer at the local children’s hospital.

People always say we should stop and smell the roses, but I didn’t really understand exactly what this meant until I was about 13 years old.

Over the next several months I became good friends with Emilio, a teenager fighting for his life, who taught me to appreciate the small things life has to offer us.
