Fair-weather friend

A person whose friendship cannot be relied on in difficult times

The most appropriate meaning of the idiom "fair-weather friend" is >A person whose friendship cannot be relied on in difficult times.<

This idiom is used to describe someone who is only a friend when things are going well. When times get tough, they are nowhere to be found. They are not someone who you can count on to be there for you when you need them most.

The other options are not correct.

• "A person who is a friend in all your difficulties" is the opposite of a fair-weather friend.
• "A person who is a friend in all good and bad times" is not a fair-weather friend, but rather a true friend.
• "A person who is not a friend, only an acquaintance" is not a fair-weather friend, but rather someone who you do not know well enough to be considered a friend.
