Could anyone explain this sentence. (I can't understand because I couldn't understand `at best')
I have already looked into dictionaries but still I can't understand it.
I hope this will help you.
At best means under the most favorable circumstances, as in At best we'll be just one week behind schedule, or Cleaning out the attic is a tedious job at best. This idiom, formerly also put as at the best, today is most often used in situations that are actually far from ideal, as in the examples above.
