I said enough is enough! 我说够了就是够了!
I can only take so much. 我只能忍受到这种程度. There's no room in the family for wimps. 我们家里容不下懦夫. I just can't swallow another one of your excuses. 我实在咽不下你的另一个借口. You did it once too often. 这种事你已做了太多, 这回我已忍无可忍. You're trying my patience. 你在惹我生气.
My patience is wearing thin. 我的耐性已快磨光了.
