Five useful expressions from my reading a novel: 1. One thing at a time. Means to deal with one thing before starting to do another. eg. There are so many problems, but let's take one thing at a time. 2. The last thing I want(need) is Means I don't want(need). eg. The last thing I want is another mouth to feed. 3. Turn a blind eye Means ignoring of undesirable information. eg. I never take a blind eye to my weakness. 4. Tricky topic Means some topic you don't want to talk about because the topic makes you uncomfortable. eg. Salary is a really tricky topic to talk about. 5. Not impossible, but slim Means it is very impossible. eg. It is very hard for me to finish this task in two days, not impossible, but slim.
