Zachary's Memory

Zachary is arrived at the end of his life and he remembers.
His memories  mix. You are the memory's archiver, and you have to sort them.
You have to type on your keyboard to create a label and sort a memory. Some of them are linked and need to have the same label, but be carefull, by mixing two memories which are not linked, you will lost the last memories and those to come which are linked with it.
