布兰特：我真的很恼火，我们把本应该到手的东西弄丢了（布兰特：我很气愤，我们竟把唾手可得的成果拱手让人）

Providing translations and rewrites

I’m thinking about how I can offer quick translations and rewrites proactively without imposing on the user. The guidelines suggest suggesting ideas only when needed. A clean English translation for "I'm really frustrated—we let something that should have been ours slip away" would be helpful. I’ll also provide a few rewrites in Chinese with different tones—subdued, ironic, and calm leadership. If it’s a script, I’ll include a line to continue the dialogue. Then I'll ask what they’d prefer next while keeping things concise.
