The exercise:
Write about: the store clerk.
Edit: looks like I've hit the limit for the unique number of labels the blog can have (2,000 in case you were wondering). Guess I'll have to get creative with the labels I already have. And maybe, if I have time, finding similar labels and gathering them under one unique label in order to free up some space. Doesn't seem like it would make much of a difference long term though.
Only took me twelve years to run into this problem...
