This is such a glaring error. How did you miss it? 这么明显的错误, 你怎会疏忽呢? That's a gross negligence. 那是个重大的疏忽. I've got to be smarter this time. 这次我得学聪明点儿. All right! All right I made a mistake. I'm only human. 得了, 得了, 我承认我犯了错. 我只不过是个凡人. I am not perfect, I make mistakes. 我并不完美,我也会做错事.
It's just an honest mistake. 这只是个无心之过. I'm not perfect. 我并非十全十美.
Live and learn. 活到老学到老.
