A lot if people are extremely self conscious about their height if they are a tall girl. It is a common insecurity except people feel the need to point it out to you constantly - especially strangers who you are speaking to for the first time.
Now imagine you are a girl self conscious about being tall and you are speaking to a hot guy and he says “whoa you’re tall”. It’s like wow fucking amazing I’ve never noticed that before in my whole freaking existence. It also feels like you’re instantly being discounted as anyone they could ever have interest in because they are too afraid to be emasculated by us.
Would you point out other insecurities to people like “hey man you have a fuck ugly face” or “hey jess have you ever realised that you’re fat and have tiny boobs?”. No you wouldn’t, stop doing it to us.
