With friend you have a lot of fun.
A friend will never let you down.
You’ll tell your secrets to your friend,
And he will always understand.A friend is always there for you,
And you can talk your problems through
And now the most important thing,
He’ll be with you through thick and thin.But if your friend just wants some fun
