Why does it take 10 months to print photos?

Historically, we've always put up prints of photos we've taken over the years on our walls.  After moving into the loft, we didn't want to simply hang up the prints we previously had at our old place.  Since that time, we've taken many new (better!) photos, and hey, it was time for a change. Why has it taken 10 months since we moved here to do this?  Well, I'd like to say we've been "busy" (read: lazy).

An unspeakable amount of time was spent choosing photos, printing, framing, mocking up the print arrangement on the wall, etc.  When everything was said and done this was the result on one of the walls in our living room...

All in all we're both happy with the result so far.  The question now is... will it take another 10 months to complete the next print hanging project?
