The file Love.txt is the original "raw" data which is used in the Basic Interlinearization lessons of the Shoebox computer based training (CBT).  This file is here for those who would like additional practice at doing basic interlinearization by duplicating the interlinearizing on their own.  

It is recommended that you first complete all the Basic Interlinearization lessons in the cbt, then, if you desire, you can use this file to do the interlinearization on your own.

Alternatively, you could have the Shoebox cbt running simultaneouly with Shoebox.  By using Alt-Tab, you could then switch back and forth between the two, following the steps in the computer based training and trying to duplicate the steps in Shoebox.  This could get confusing so is only recommended for advanced computer users.
