We'll Talk One Day, Jenny

Jenny and Lady have always been best friends since fifth grade. They always knew each other so well it seemed like they were the same person. One day, Jenny had to leave. She later on moved away and left Lady all alone.
Both girls grew older and both went on to college. Later on in the year Lady starts to receive letters from Jenny. The girls haven't talked in many years so it confused Lady due to the lacking of information in the letters. The letters are nothing but small fragments of what seems to have happened in fifth grade. They even have the hand writing of when Jenny was young.
Some words, even sentences have been erased or either scratched out. Most have a date on them. These letters are so old most the writing has faded. But the dates seem to have been written on recently.
Lady really misses Jenny. She would love to talk to her again but she can't help but get an uneasy feeling about these letters.
All though, they did always stick by a promise they kept around. "We will talk later."
Unfortunately, that task seems a bit, impossible now.
