Why we need friends?

We need friends for many reasons,
all throughout the four seasons.

We need friends to comfort us when we are sad,
and to have fun with us when we are glad.

We need friends to give us good advice.
We need someone we can count on to treat us nice.

We need friends because we are social in nature,
and having friends makes us feel secure.

We need friends to remember us once we have passed
sharing memories that will always last.

This is my opinion. Please give your opinion. Why we need friends?
