Fortunately, our friend John offered very kindly to let us borrow his Toyota Tundra pickup on short (i.e., no) notice. Unfortunately, he needed it back by 6:30 PM that evening, so we needed to hurry, as it was already after 3:30 by this point!
While both vehicles are Toyotas, it turns out there's a world of difference between driving my Corolla and John's Tundra. I could feel my testosterone levels rising the moment I hoisted myself up into the drivers seat and sat behind the wheel of the truck. Before long I found myself grunting a lot and saying things like "I will crush you, puny Nissan!"... but that's another story. Still, I had no doubt that my newly elevated manliness was making me irresistible to Heather.
We got home with a truck full of flooring at about 5:20, which by our calculations meant that we had about 20 minutes to unload all 22 boxes, carry them up the flight of stairs to our apartment, and stash them somewhere where they wouldn't be too much in the way for the next month and a half.
One of the many amazing things about Heather is how freaking capable she is. Not only did she quickly identify a number of out-of-the-way places to stash the boxes, but she unloaded at least half of the boxes herself, including carrying each one up a flight of stairs singlehandedly in 90°+ weather. I had to work hard just to keep up with her!
In the end, we got all of the boxes unloaded in about 25 minutes and made it back to Garner to return the truck with a few minutes to spare - success!
