Telephone Directory Follies

Last week the annual update of phone number directories from AT&T was delivered to my condo complex. All well and good, I just need to remember to get the old directories to recycling.

Then this morning I step outside to get to work, and what do I see. Another delivery of the new AT&T directories. Oh joy, now I'll have twice as many directories to get to recycling. (Sigh)

So, what brought this about? Right now I can think of two possibilities, both of which seem far-fetched, but nothing else occurs to me:

1. The contractor AT&T hired to make the deliveries to my area somehow lost track of where they had left the new directories and went back over areas they had already covered.
2. AT&T has more than one contractor making deliveries to overlapping areas.
