It's super fucking unsettling. I actually was recording a video of my cats when it happened, and I can clearly hear the impact sounds. I'm monitoring local fire department responses to try to learn more. I really hope I didn't just record the sound of someone dying. :(

but the crucial, must-not-skip next step after this realization is actually doing something to work on it instead of adopting it as an immutable personality trait you pretend is cute because it makes you seem vulnerable and introspective, and thereby making it Everybody Else's Problem.

Yes, the stubborn little scamps!
