To Rob
This thing is now in a faraway land
The Druids gave it before they went.
Our family passed it from father to son
It is one in seven , there are seven in one.
Once it brought death,
Once it showed the way,
Once it brought wealth,
Once it saved the day,
Once it brought love,
Once it brought hope,
Once it brought peace to the fighting folks.
It was king to some people and it made some cry.
But for worse or for better it saved their lives.
But they lost thing and the treasure got lost.
Find the seven keys and the treasure is yours.

I did not go this summer on the sea. But I spent many of times with my grandmother. I helped her in the kitchen garden and in the house. I often walked with my young brother. I engaged the chemistry, read the book, watched TV in the free time. At first was rainy weather, then it was sunny. However I liked this summer.
