Talk about the tone of the following sentence.

1, I don't think about whether I can succeed or not. Since I chose the distance, I only care about hardships; I don't think about whether there will be cold wind and rain behind me. Since the goal is the horizon, what is left to the world is only the back.

2. Many times, we don't look at our parents' backs, but bear their chasing eyes and their unwilling, uneasy and eyeful eyes. Finally, I gradually realized that no one in this world can love me as much as my parents and life.

You left with all my love. It's just a breakup I look at your back with tears in my eyes, and I really want to hug you for the last time. I really want to say "I love you" to you again

4, love, extending in my mind; Love deepens in my heart; Miss, plug in the wings of flying; My hope shines on the hotbed of Egypt; Your back has become the direction I pursue.

I'm glad I'm nearsighted. I couldn't even see my back clearly when you left.

I want to walk with you! But all you left me was your back, and the back you walked side by side with others.
