Was this an Owl fantasy? You know one where Owl passes so well as a woman that even her older female t*rf neighbour doesn't realise Owl was a man, despite spying on Owl over the wall and fence all the time. Owl doesn't mind the stalking and lets neighbour catsit. Obviously needs to spend more time on AIBU does Owl.
Anyway, in Owl's fantasy, neighbour is astonished to discover Owl is not XX when confronted by Owl about transphobia. Of course there is no chance of the trans topic coming up in conversation to enable this super-validating exchange because Owl totally passes so plot device needed.
Owl has trans friends round for a picnic, they don't pass like Owl does, Owl transes better than them you see. Stalker neighbour peers over the wall as always and sees the trans people who aren't as good at trans as Owl. Later the neighbour has a little moan on the phone about how trans people never pass. She has this phone call while outside in the garden right by the fence but doesn't see Owl because of the washing. Don't we all hang our sheets up to dry on the washing line right along the boundary fence with our neighbours? Owl confronts and is validated.
Owl reflects on how she is definitely a real woman because a transman once got drunk and pushed her over, in the style you sometimes see in anti-DV videos. Transman is validated too. He is so big and strong he can push Owl to the ground and scare Owl. He looks big by being right by the camera and Owl looks smaller on the ground far away. Owl has seen Father Ted and the talk about the cows you see.
TLDR: Adrian Mole made a video.
