It happened a few weeks ago.

I was walking with my sister Mary along the street and we were talking.It was late,about 8 o'clock.Suddenly, we saw a starnge man who was climbing through the window to the nearest house.My first though was that it was a burglar and we called up the police.While I was waiting with my sister near the house,we were observing the man who had already gone inside the building.When the police arrived,I explained them everything once again.Then the policemen entered the house.After some while they appeared in front of me with huge smiles and with the stranger.They explained me thatit was owner of the house who had forgotten the key.I was shocked and embarrassed.My sister was confused and she was laughing at our reaction.Also the other men were smiling.I'll never forget that incident.
