Storage Units

Storage units intrigue me.  Here's why:

1.  I think manning the desk at a storage unit would be a stress-free job, vs. teaching 24 5th graders daily.
2.  They look so neat and organized on the outside.
3.  There are so many of them in town and that wasn't the case 15 years ago.  Houses are so much bigger now as well...why so many storage units?
4.  Why pay hundreds (maybe over a thousand) dollars a year to store stuff? 
5.  Is it really that important to pay to store stuff?  I can see temporarily storing items while you are in-between homes and maybe renting a small apartment, but...
6.  People stop paying and other people can buy their stuff.  Guess they didn't need it that badly to be paying for a storage unit, huh?

And that's why storage units intrigue me.  The end.  (my students are working on getting past these kinds of composition endings right now...you see, I haven't pursued a desk job at a storage unit yet.)
