awww, don't beat yourself up, we all miss some cue's sometimes. Because our 3 sleep with us, the "GET UP I HAVE TO PEE!" cue is nearly impossible to miss.
If a gentle tapping on my face doesn't work, they just climb up and sit on my head until I get up.
But I've missed some of their "asking" when I'm preoccupied, say when I'm on YT.
