粗心

今天早上在去学校的路上我犯了一个错误。也许是因为我在等公交车去学校的时候还有点困。我太粗心了，所以就上错车了。而我却没有发觉。十分钟后，我看了看窗外，发现路跟我平时走的路不一样。

Last week, I lost my umbrella when I got off the bus. I felt so sorry for being so careless.

Today, I do something stupid because of my carelessness. I take a bus to school every morning. But today, I was on the wrong bus and I realized it ten minutes.
