There was a bloke who went to great lengths to present as a lizard. He was in the US, had lots of surgery and tattoos and piercings. He eventually looked very striking, but, he wasn't what he believed he wanted to be.
There was a UK based woman who believed she was a cat. Similar issue but with fewer permanent adaptations but a big old tail that attached, I expect, in the usual manner.
Neither of these people were what they genuinely wanted to be. And I have sympathy for that. However, reality persists.
Life is happier if you recognise that (in my case) I am not 6'4" tall but some inches are mysteriously invisible to others, I am just short and fat. Yes, if I was tall I'd be the right weight for my height, yes I'd love to wear flowing bias cut chiffon, but, I can't. Well, I could, but I'd look fucking ridiculous. It's better to accept that than to persuade the whole world that I belong at London Fashion Week, modelling some sample on one calf that I lump down the cat walk.
