"踏着轻快的脚步回家"

When I was young, I always wrote "踏着轻快的脚步回家" to finish off my Chinese composition. Then I will score an A for it. As said by my Chinese teacher.

Then I realize as I grew up, no such thing as "踏着轻快的脚步回家" because everyday I will be exhausted. How am I to do that when always squeeze myself with the crowded train cabins? In fact, I will drag my heavy feet home.

That time when we were so innocent and pure.

Now we are so hasty and impulsive.
