Real friendship is shown in times of trouble; prosperity is full of friends

Prosperity is full of friends.

I would prefer as friend a good man ignorant than one more clever who is evil too.

Only when you are in trouble do you realize who your true friends are… And, my dear, you will be surprised!

Friends show their love - in times of trouble, not in happiness

It destroys one's nerves to be amiable everyday to the same human being.
