I was sitting inside at the new house I'm moving to, while the water purification system was being signed for/paperwork done. I started carrying boxes from the car inside, and afterwards I sat down again and enjoyed myself on the deck outside, watching a spider weave its web on the top of the deck off to the side. I heard a car pull out, and seen it was the water company. So I went downstairs to ask when they're gonna be installing it, and apparently they left behind some testing equipment! xD They haven't even come back for it yet, which is hilarious. Then, the next day, internet was installed, and the same thing happened! They left behind some cables/spool of cables.

If this keeps up, I bet the next person will leave something behind haha!
