求翻译：我曾无数次在校园里漫步。然而每一次，我都在想自己的心事，周围的一切似乎都与我无关。然而今天的漫步，我却要睁大眼睛，好好看看这个校园。我要把校园里每一朵花每一棵草都镌刻在我的记忆里。是什么意思？

I have numerous walks on the campus. But each time, my mind and I think, everything around seems to has nothing to do with me. However today's walk, my eyes, take a look at this campus. I want to put each flower grass on campus are engraved in my memory.
