Cách sử dụng
The expression "at the best of times" is used to describe a situation or experience that is already good or positive, even when everything is going well. For example, if someone says "I find it hard to sleep at the best of times," they mean that even when things are going well, like when they aren't stressed or anxious, they still struggle to sleep. This expression is used to emphasize that something is even more challenging or difficult than usual when it is not the best of times.
