年少无知的我们，做错了许多事。

Ignorance of us, many things wrong.

可我，那时年少无知，如今悔泪滔滔。

But I was young and foolish, and now I'm full of tears.

拿我来说吧，当我还年少无知时，我常常听说“收费站前设有减速带是为了让那些眼神不好的司机有多点时间找零钱”。

For example, "Those speed bumps are put in front of tollbooth plazas so that hard-of-seeing drivers will have more time to find exact change, " is one I was exposed to at a tender time of life.
