String-and-tin-can-phone Love

"The phone extended from island to island. It had to pay out more and more string, as if letting kites go higher and higher. The string between the boy and girl grew incredibly long, so long it had to be extended to many strings together. Containing within everything they shared with one another. They had more and more to tell eachother, and less and less string.
The girl said 'I love you' into her can. The words traveled the yo-yo, the doll, the diary, the necklace, the birthday present, the harp, the teabag, the tennis racket, the hem of the skirt he one day would have pulled from her body.
The boy covered his can with a lid, removed it from the string, and put her love for him on a shelf in his closet. Of course, he never could open the can, because then he would lose it's contents. 
It was enough just to know it was there."
