A HAPPY STORY:

A man was walking in the park when he felt tired.

He was sitting on a bench when he found a wallet.

He didn´t know what to do.

He thought of looking for a contact while he was going home.

He saw a number while he was searching the wallet.

He phoned a relative and he came to pick the wallet.

The man and his son were waiting when the bell rang.

The owner was happy to recover it because he had had trouble...
