I am deeply sorry for this, I hope you can understand me, I also believe that this will not affect our friendship.
Finally, let me this evening to give you the best wishes: Happy birthday to you!
Your friends
Dear
I am terribly sorry to tell you that I have lost the valuable book you were so kind to lend me last week. I read it everyday and intended to finish it next month. Last night when I came to my room, it was nowhere to be found. I will try to recover it as soon as possible. If I fail to find it, I will get a new book for you.
But I am afraid it can never take the place of the old one. Old books are like old friends. Once lost, they can never be replaced. They are connected with cherished associations which the new ones can never have. And for this irrecoverable loss, I am to blame. I was so careless with my things. This is a warning to me to be more careful in the future.
Yours truly,
机械有限公司领导，您好!
感谢您多年来对我公司的一贯信任和厚爱!正是有了您的支持与帮助，才使我们在困难重重的不利形势下得以坚持下来，以专业精神和高度负责的态度为您提供优质的产品。您知道，今年以来，到处都出现了严重的“用工荒”，我公司也不例外，春节过后，上工率严重下降，虽然我们几经创造条件，陆续招收了一批批员工，但到目前为止，仍未恢复到去年的水平。
我们是专业厂家，不仅制造设备要精良，员工的操作技术更要过硬，而对于新工，我们必须用足够的时间和精力进行操作技术培训，没有技术的员工，我们是不能允许上岗实际生产的。在产品上，我们宁愿做少一些，决不能做差一点。对此，想必您也认同。
今年以来，当地政府进一步加大节能减排举措，使我们雪上加霜，许多企业受到停电、限电、停水等严重困扰，到目前为止，我们这一区域仍然隔一天一供电，已经存续很长时间;不仅我公司受到极大的影响，就连我们的很多上线供应商也因此经常拖延供货。让人难堪的是，我们本来不得不压缩的生产计划，常常难以完成。对此，我们万分焦急!
值得高兴的是，我们招收的新工经过数月培训，已经陆续合格上岗;我们的发电机也已经调试发电，使我们得以有效克服停电、限电的困难;对于上线供应商，我们已经落实了帮扶措施，想必今后基本可以正常供货。按下来的下半年，我们将基本具备正常生产的能力，力争将产品产量恢复到去年水平。
尊敬的老朋友，贵司是我们的老客户，多年来，给了我们极大的支持和厚爱，我们理应以高质量的产品、及时的交期予以回报。但今年以来，由于我们的无奈，给贵司造成了极大的不便，对此，我们深表遗憾!
接下来，随着我们产量的不断提高，我们将把贵司作为我们的优先供货客户，按质、按量，准时交货，通过我们的实际行动，表达我们诚挚的歉意!
希望能够得到您和贵司的谅解，并一如既往给我们信任和支持!再次感谢!
