If you've ever been a kid, you should know what this piece is about before getting to the ending

It was a bright, sunny day, not one cloud touched the crystal blue sky. The sun cast cheerful rays full of optimism and hope. Every living thing seemed to be abuzz with energy, singing a song of great anticipation, for today was the day I was going to face my greatest fear.  For everyone else, it was just a typical Sunday afternoon that would be used for lounging around without a worry. But for me, the day was one I have been dreading for a long time (which was probably only a few days, but it felt like months).
I waited on the couch, nervously twiddling my thumbs with anxiety, dreading what was to come. I had only minutes left before my father would come in, ready to get it over with. After what seemed like an eternity, he finally came to take me outside to face my fear. As I walked outside, I stared fearfully at the thing I was convinced would end my life.
There it stood, mocking me with its bright yellow colors, daring me to come closer. “Are you ready?” He asked. I wearily nodded my head, not wanting to let on how terrified I really was. He sat me atop of it, holding onto the back so that I wouldn’t topple over. After a long while of refusing to go, I started moving, ever so slowly, along my driveway. I started to move a little bit faster, my dad holding on and running behind me. This isn’t so bad, I thought. Maybe I can do this. But then, my confidence was shattered to pieces as soon as I heard my dad yell “Let’s try letting you go on your own!” A surge of fear and panic swept through me, like a huge bubble of air rising to the surface of a lake, bringing up with it a sudden welling of tears in my eyes.
“No! Please! Don’t let go!” Tears were stinging my eyes now, streaming back across my face as the wind wiped them away with its harsh gust of air I felt while increasing speed. “You can do it! Ready; 1...2...3!” and then he let go. I screamed, but kept going. For the sake of not falling, for the sake of making my dad proud, I kept going. I was certain that I was going to fall now. The once happily chirping birds were now screaming in warning. The once cheerful rays of sun were now harsh and blinding.
I squeezed my eyes shut, preparing for the fall. 1...2...3…….4? I’m still going? I forced my eyes open, noticing that I was still aloft. “Yes! Yes! Keep going!” I heard my dad yell behind me. The wind whipping past me was no longer terrifying, but exhilarating. I felt a powerful sense of freedom and independence as I moved along, welcoming the bright rays of sun, and the electrifying gusts of wind whipping my long hair behind me.
I slowed down and made a U-turn, then exuberantly went back to my dad. I slowed to a stop and jumped off, right into my dad’s arms. He congratulated me, and I could hear my mom cheering from the window. A wave of euphoria took over me as I hopped back on and did a victory lap. I finally learned how to ride a bike.
