Hmm... It's 11:13 p.m., and "Mommy" of the Banging Brood should be at work. Should be, but isn't. And instead of keeping her unruly brood from thumping that ball, she's letting them do whatever they want. Or they'll whine about it.
"Mommy" tried to say it wasn't them, but that's bull. I can hear them against the shared wall. Confiscate that stupid ball and leave it at that.
I think I let them know that I was pissed.
