请帮我翻译一下一句英文好吗

Since done, the other on the right, I promise, okay?

since you cant do it,dont make a promise to me,all right?

挺对的了。。

既然办不到,就别对我承诺,好吗?
Don't promise me unless you can do it, will you?

since you can not make it,please don not make a promise to me,ok?
也可以这样子说:If you can not follow through.don not make a promise to me .aii right?
个人比较喜欢后面一句，比较与众不同．

Since you can not do it,don`t promise anything to me,okay?

Since you can't manage it,please don't make any promises ,will you?
