A friend that helps you when you need is a good friend.

One swallow doesn't make a summer:

One event does not define the other, we must not create expectations.

An apple a day keeps the doctor away:

Eating fruits is good for your health.

Too many cooks spoil the broth:

You don’t need too many people to do somethings as it turns out to be worst.

Don't judge the book by its cover:

You cannot judge things by what they appear to be.

Better late than never:

It’s preferable that something good happens late than never.

It's no use crying over spilled milk:

It's no use Crying when a mistake is made.

A bird in the hand is worth in the bush:

We need to value what we have.
