"Why couldn't it have been delivered straight there?"
"There won't be anyone there."
As we don't have a forklift the only way to get it on the van is for them to break open the packing and lug the stuff on a box at a time. They then drive over to the Centre to find that someone's on site eight to five every day. When they get back they mention this to Mary.
"Well, I wanted to see what it looked like when it arrived anyway."
It looked like a couple of big cardboard boxes stuck on palettes. I hope that assuaged her curiosity.
