Another one of theirs that comes to mind is "Audience of One". An excerpt from the middle verse and chorus:
Identities assume us. As 9 and 5 add up. Synchronizing watches to the seconds that we lost. I looked up and saw you, and I know that you saw me. We froze but for a moment... in empathy. I brought down the sky for you and all you did was shrug. You gave my emptiness a name.
Then you ran away. Now all my friends are gone. Maybe we've outgrown all the things that we once loved. Run away, but what are we running from? A show of hands from those in this audience of one. Where have they gone?
I've had both the CatGenie and the Litter Robot 4. While the novelty of a washable cat litter made the CatGenie appealing and I used it with my two cats for a few years, it was just prone to not collecting all of the droppings and then air drying it, smelling up the whole house. Cleaning it was also a huge and disgusting pain in the ass when it got clogged up.
The Litter Robot 4 is significantly better. It's quiet, easy to refill, cycles quickly, and with the newer firmwares being put out, is less prone to false positives with its sensors. The only iffy thing is still the full Litter drawing sensor saying the drawer is more full than it really is, but it's a minor annoyance.
